Primer reto

Challenge completed!

import 'dart:math';

void main() {
	List<int> ages = [33, 15, 27, 40, 22];
  
  print("La edad mayor es: ${ages.reduce(max)}");
  print("La edad menor es: ${ages.reduce(min)}");
  print("La edad promedio es: ${ages.reduce((c, i) => c + i) / ages.length}");
}

🎈 Este reto me sirvió para poner en práctica lo que aprendí sobre Dart.

void main() {
  List<int> ages = [33, 15, 27, 40, 22];
  ages.sort();
  print('''
  Lista de Edades: ${ages}
  Edad Mayor: ${higher(ages)}
  Edad Menor: ${less(ages)}
  Edad Promedio: ${average(ages)}
  ''');
}

int higher(List<int> ages) {
  int age = ages[0];
  for (int index = 0; index < ages.length - 1; index++) {
    if (ages[index + 1] > age) {
      age = ages[index + 1];
    }
  }
  return age;
}

int less(List<int> ages) {
  int age = ages[0];
  for (int index = 0; index < ages.length - 1; index++) {
    if (ages[index + 1] < age) {
      age = ages[index + 1];
    }
  }
  return age;
}

double average(List<int> ages) {
  int sum = 0;
  for (int age in ages) {
    sum += age;
  }
  return sum / ages.length;
}

Qué bonito es Dart, nunca había programado en él y me pareció asombroso. Aquí dejo mi código:

Saludos!

void main() {
  var ages = [33,15,27,40,22];
  ages.sort();
  print('''
  La edad mayor es ${ages.last}'
  La edad menor es ${ages.first}'
  La edad promedio es ${ages.reduce((v,e)=>v+e)/ages.length}''');
 }```

void main() {
  List ages = [33, 15, 27, 40, 22];
  ages.sort();
  print('Menor: ${ages.first}');
  print('Mayor: ${ages.last}');
  print('Promedio: ${ages.reduce((value, element) => value + element)/ages.length}');
}

Reto Cumplido 😃

void main(){
  int edadMayor,edadMenor;
  var ages = [33, 15, 27, 40, 22];
  int i=0,s=0;
  edadMayor=ages[ages.length-1];
  edadMenor=ages[ages.length-1];
  while(i<ages.length){
    if(ages[i]>edadMayor){
      edadMayor=ages[i];
    }
    if(ages[i]<edadMenor){
      edadMenor=ages[i];
    }
    s=s+ages[i];
    i++;
  }
  print('La edad mayor es: $edadMayor \nLa edad menor es: $edadMenor \nLa edad promedio es: ${s/ages.length-1}');
}

void main() {
  var ages = [33, 15, 27, 40, 22];
  
  double avg = 0;
  for (int i = 0; i < ages.length; i++) {
    avg += ages[i] / ages.length;
  }
  
  ages.sort();
  print('Max is ${ages.last}');
  print('Min is ${ages.first}');
  print('Avg is $avg');
}```

void main() {
  var ages = [33,15,27,40,22];
  
 ages.sort();
  print(ages);
  print("La edad mayor es ${ages.last}");
  print("La edad menor es ${ages.first}");
  print("La edad promedio es ${ages.reduce((x, z) => x + z) / ages.length}");
}

// "La edad Menor es: 15"
// "La edad Promedio es: 27"
// "La edad Mayor es: 40"

Mi código quedó así:

void main() 
{
  var ages = [33, 15, 27, 40, 22];
  var mayor = ages[0];
  var menor = ages[0];
  var sumaNumeros = 0;
  var promedio;
  for (int i = 0; i < ages.length ; i++) 
  {
    if(ages[i] < menor)
    {
      menor = ages[i];
    }
     if(ages[i] > mayor)
    {
      mayor = ages[i];
    }
    sumaNumeros += ages[i];
  }
  promedio = sumaNumeros/ages.length;
  print("La edad mayor es: $mayor \n" +
        "La edad menor es: $menor \n" +
        "La edad promedio es: $promedio");
}

void main() {
  List <int> ages = [33,15,27,40,22]; 
  ages.sort();
  var dimen = ages.length; 
  var mean = ages.reduce((a,b) =>a + b)/dimen; 
  print('El valor menor es ${ages[0]}');
  print('El valor mayor es ${ages[dimen-1]}');
  print('El valor de la media es ${mean}');
  
}

void main() {
var ages = [33,15,27,40,22];

ages.sort();
print(ages);
print(“La edad mayor es ${ages.last}”);
print(“La edad menor es ${ages.first}”);
print(“La edad promedio es ${ages.reduce((x, z) => x + z) / ages.length}”);
}

Usando un poco ayudas en Dart XD

import 'dart:math';
void main() {
  var ages = [33,15,17,40,22];
  print('La edad mayor es: ${ages.reduce(max)}');
  print('La edad mayor es: ${ages.reduce(min)}');
}

void main() {
  var ages = [33, 15, 27, 40, 22];
  ages.sort();
  
  var average = ages.reduce((value, element) => value + element) / ages.length;
  
  print("The oldest age is: ${ages.last}");
  print("The youngest age is: ${ages.first}");
  print("The average age is: ${average}");  
}

Codigo

void main() {
  var ages = [33, 15, 27, 40, 22];
  dynamic less = ages[0];
  dynamic more = ages[0];
  dynamic sum = 0;
  for(int i = 0; i< ages.length; i++){
    less = (ages[i] < less)? ages[i] : less;
    more = (ages[i] > more)? ages[i] : more;
    sum += ages[i];
  }
  dynamic prom = sum/ages.length;
  print('La edad mayor es: $more');
  print('La edad menor es: $less');
  print('La edad promedio es: $prom');
}

Consola

La edad mayor es: 40
La edad menor es: 15
La edad promedio es: 27.4

void main() {
  
  var ages = [33, 15, 27, 40, 22];
  	ages.sort();
  print(ages);
 
  print('La edad mayor es: ${ages.last}');
  print('La edad menor es: ${ages.first}');
   var sum = 0;
  for (var num in ages) {
    sum = sum + num;
  }
  var promedio = sum/ages.length;
   print('El promedio es: $promedio');
}

Así lo resolvi yo.

void main() {
  var ages = [33, 15, 27, 40, 22];
  ages.sort();
  
  var min = ages[0];
  var max = ages[ages.length - 1];
  dynamic avg = 0;
  
  ages.forEach((age) {
    avg += age;
  });
  avg = avg / ages.length;
  
  
  print('Edad Mínina: ${min}');
  print('Edad Máxima: ${max}');
  print('Edad Promedio: ${avg}');
}


//Edad Mínina: 15
//Edad Máxima: 40
//Edad Promedio: 27.4

void main() {
  var ages = [33,15,27,40,22];
  ages.sort();
  var suma = 0;
  for (var i=0; i<ages.length; i++){
    suma = suma + ages[i];
  }
  var promedio = (suma/ages.length);
  
  print('''El arreglo ordenado es: ${ages}
  La edad mayor es ${ages[ages.length-1]}
  La edad menor es ${ages[0]}
  La edad promedio es ${promedio}
         ''');
}

Mi solución:

var ages = [33, 15, 27, 40, 22];

void main(){
  //Order ages
  ages.sort();
  print('La edad mayor es: ${ages.last}');
  print('La edad menor es: ${ages.first}');
  
  //Average calculation
  int total = 0;
  double average = 0;
  ages.forEach((item) {
    total = total + item;
  });
  
  average = total/ages.length;
  print('La edad promedio es: ${average}');

}

void main() {
/*Declaración de variables*/  
  var edades = [33,15,27,40,22];
	var edadMayor = 0;
  var edadMenor = 0;
  var cuentoEdades = 0;
  dynamic edadPromedio = 0;
/*Inicio del primer for para comparar edades mayores*/  
  for(int i = 0; i<=4; i++){
    if(edades[i] > edadMayor) {
    	 edadMayor = edades[i];
    }else{
      edadMenor = edades[i];
      /*Comparo edades Menores*/
      for(int i = 1; i<=4; i++){
        if(edades[i] < edadMenor){
          edadMenor = edades[i];
        } 
       }
     } 
    cuentoEdades += edades[i];
   }
	edadPromedio = cuentoEdades/5;
   print("La edad mayor es: $edadMayor");
  print("\n La edad menor es:  $edadMenor");
  print("\n La edad promedio es:  $edadPromedio");
}

Esta es mi solución… 😃

void main() {
  
  var ages = [33, 15, 27, 40, 22];
  var sum = 0;

  ages.sort(); //ordenar la lista
  ages.forEach((age) => sum += age); //recorre la lista y suma las edades 

  print('La edad menor es ${ages[0]}');
  print('La edad mayor es ${ages[ages.length - 1]}');
  print('La edad promedio es ${sum/ages.length}');

}

void main() {
  var ages = [33,15,27,40,22];
  double promedio = 0;
  
  ages.sort();
  ages.forEach((edad) => {promedio = promedio + edad});
  
  print("La edad mayor es ${ages[ages.length-1]}");
  print("La edad menor es ${ages[0]}");
  print("La edad promedio es ${promedio/ages.length}");

}```

  void main() {
  var ages = [33,15,27,40,22];
   //ordenar  menor a mayor
  ages.sort();
   
  int suma = 0;
   //calcular suma del vector edades
  ages.forEach((x) { suma += x; });
  
  print("La edad Mayor es ${ages[ages.length - 1]}");
  print("La edad Menor es ${ages[0]}");
   //Calcular Promedio
  print("La edad promedio es ${suma/ages.length}");
}
  

Recuerden que siempre puede que alguien ya tenga una funcion para ello, solo hace falta importar la libreria =D

import 'dart:math';
void main() {
  
  var ages=[33,15,27,40,22];
  
  int maxAge = ages.reduce(max), 
      minAge = ages.reduce(min);
  
  print('max: $maxAge' "\n" "min: $minAge");
  
 }

Hola!, aquí está mi código:

void main() {
  var ages = [33, 15, 27, 40, 22];

  ages.sort(); // Organizamos la lista
  var sum = 0;
  
  print('Min age is: ${ages[0]}');
  print('Max age is: ${ages[ages.length - 1]}');
  ages.forEach((it) => {
    sum += it
  });
                       
  print('Avg age is: ${sum / ages.length}');
  
}```

main() {
  var ages = [33, 15, 27, 40, 22];
  ages.sort();
  var prom =  ages.reduce((current, next) => current + next);
  print('La edad mayor es: ${ages.last}');
  print('La edad menor es: ${ages.first}');
  print('La edad promedio es: ${prom/ ages.length}');
} 

void main() {
  var ages = [33, 15, 27, 40, 22];
  ages.sort();
  int menor = ages.first;
  int mayor = ages.last;
  double prom = 0;
  
  var sum = ages.reduce((a, b) => a + b);
  var promedio = sum / ages.length;
  
  print("La edad mayor es: $mayor");
  print("La edad menor es: $menor");
  print("El promedio es: $promedio");
}

void main() {
  List<int> ages = [33,15,27,40,22];
  ages.sort();
  print('La edad menor es: ${ages.first}');
  print('La edad mayor es: ${ages.last}');
  print('La edad promedio es: ${ages.reduce((a,b) => a+b)/ages.length}');
}

void main() {
  var ages = [33, 15, 27, 40, 22];
  ages.sort();
  print('El menor tiene ${ages.first} años');
  print('El mayor tiene ${ages.last} años');
  print('La edad promedio es ${(ages.reduce((value, element) => value + element))/ages.length}');  
}```

void main() {
  var ages=[33, 15, 27, 40, 22];
  ages.sort();
  print('la edad menor es: ${ages[0]}');
  print('la edad mayor es: ${ages[ages.length-1]}');
  var sum = ages.reduce((a,b)=>a+b);
  print('la edad promedio es: ${sum/ages.length}');
}

Les adjunto mi reto

void main() {
  List<int> list = [33, 15, 27, 40, 22];
  int suma = 0;
  list.sort();
  list.forEach((element) => suma += element);
  double prom = suma / (list.length);
  print('La edad mayor es: ${list[list.length - 1]}');
  print('La edad menor es: ${list[0]}');
  print('La edad promedio es: $prom ');
}

void main() {
  var ages = [33, 15, 27, 40, 22];
  ages.sort();
 
  int average = 0;
  ages.forEach((val) => average += val);
  average = average ~/ ages.length;
  
  print("El menor es ${ages.first}");
  print("El mayor es ${ages.last}");
  print("El promedio es $average");
}

void main() {
  var ages = [33, 15, 27, 40, 22];
  var mean = 
  
  ages.sort();
  
  var avg = ages.reduce((a,b)=> a+b) / ages.length;
  
  print("La edad menor es: "+ ages[0].toString());
  print("La edad mayor es: "+ ages[ages.length-1].toString());
  print("El promedio de edad es :"+ avg.toString());
  
}

Esto pasa cuando no conoces el método sort >> jajaja

void main() {
  
  var ages = [33, 15, 27, 40, 22];
  int max = 0;
  int min = 0;
  int sum = 0;
  double pro = 0;
  
  min = ages[0];
  
  for (int i=0; i < ages.length; i++) {
    
    sum += ages[i];
  
    if (ages[i] > max) {
      max = ages[i];
    }
    
    if (ages[i] < min) {
      min = ages[i];
    }
  
  }
  
  pro = sum / ages.length;
  
  print('La edad mayor es ${max}');
  print('La edad menor es ${min}');
  print('La edad promedio es ${pro}');

}```

Aquí mi solución

void main() {
  var ages = [33, 15, 27, 40, 22];
  
  int edadMayor = 0;
  int edadMenor = ages[0];
  double edadPromedio = 0;
  
  for(int i = 0; i < ages.length; i++){
    if (edadMayor < ages[i]){
      edadMayor = ages[i];
    }
    
    if (edadMenor > ages[i]){
      edadMenor = ages[i];
    }
    
    edadPromedio += ages[i];
  }
  edadPromedio = edadPromedio/ages.length;
  
  print("La edad mayor es: $edadMayor");
  print("La edad menor es: $edadMenor");
  print("La edad promedio es: $edadPromedio");  
}

  }

  ages.sort();
  print('La edad mayor es: ${ages.last}');
  print('La edad menor es: ${ages.first}');
  print('La edad promedio es: ${ages.reduce((a, b) => a + b) / ages.length}');
}

void main() {

  List<int> ages = [22,15,27,40,22];

He tenido que buscar info porque estoy empezando pero ha sido satisfactorio.

void main() {
  var ages = [33, 15, 27, 40, 22];
  ages.sort();
  double average = 0;
 
  for(int i=0; i < ages.length; i++){
    average += ages[i];  
  }
  
  print("""
  La edad mayor es: ${ages.last}
  La edad menos es: ${ages.first}
  La edad promedio es: ${average / ages.length}
  """); 
}```

Mi solucion con lo poco que recuerdo de C++

void main() {
  var ages = [33, 15, 27, 40, 20];
  var mayor = ages[0];
  var menor = mayor;
  double promedio = 0;
  
  
  for (int i = 0; i < ages.length; i++) {
    promedio += ages[i];
    if( ages[i] > mayor){
      mayor = ages[i];
    }
    if(ages[i] < menor){
      menor = ages[i];
    }
  }
  promedio = promedio / (ages.length +1);
  print("Edad menor: ${menor}");
  print("Edad mayor: ${mayor}");
  print("Edad menor: ${promedio}");
}

import 'dart:math';
void main() {
  List<int> ages =[33, 15, 23, 2];
  int maxval = ages.reduce(max);
  int minval = ages.reduce(min);
  
  
  print('La mayor edad es: $maxval');
  print('La menor edad es: $minval');
  print("La edad promedio es: ${(ages.reduce((a, b) => a +b))/ages.length}");
   

}```

Mi solución al reto. Use el método sort para organizar la lista de menor a mayor, las propiedades first y last para obtener la edad menor y la edad mayor y para sacar el promedio use el método reduce que la guarde en una variable double llamada prom.

void main() {
  var ages = [33,15,27,40,22];
  ages.sort();
  double prom = ages.reduce((value, element) => (value + element)) / ages.length;
  print('La edad menor es: ${ages.first}');
  print('La edad Mayor es: ${ages.last}');
  print('La edad promedio es: ${prom}');  
}

import 'dart:math';

void main() {
  var ages = [33, 15, 27, 40, 22];
  var sum = ages.reduce((acc, current) => acc + current);
  
  print('La edad mayor es: ${ages.reduce(max)}');
  print('La edad menor es: ${ages.reduce(min)}');
  print('La edad promedio es: ${sum / ages.length}');
}

void main() {
  var ages = [33, 15, 27, 40, 22];
  ages.sort();
  var sumTotal = ages.reduce((a, b) => a + b);

  print("The greater age:${ages[ages.length-1]}");
  print("The minor age:${ages[0]}");
  print("The average is: ${sumTotal/ages.length}");
}
