# mayorX_Y by Cecilia Lee

Implementar la función “mayorX_Y”, que recibe una matriz, y es verdadera cuando:
todas las filas Xi son mayores que alguna columna Yi
Una fila es mayor que una columna cuando la suma de sus números es mayor.
Por ejemplo, sea la matriz m:
{10,20,30},{10,20,30},{10,20,30}

boolean cond1=false;
boolean ret = true;

for(int x=0; x< matriz.length;x++){//Recorre filas
for(int y=0; y< matriz[0].length; y++){
sumF = sumF + matriz[x][y];
}//al salir de este for sumF contiene la suma de la fila actual
for (int i =0;i<matriz[0].length;i++){//al salir de este for sumaCol contiene la suma de la columna
sumC= sumaCol(matriz,i);
//System.out.println("con: " + sumC);
cond1=cond1 || sumF>sumC;
sumC=0;
}//sale de la columna
ret = ret && cond1;
cond1=false;
sumF=0;
}
return ret;
}

static int sumaCol(Integer[][] matriz, int col){// devuelve la suma de una columna
int suma=0;
for (int fila=0;fila<matriz[0].length;fila++){
suma = suma + matriz[fila][col];// col es un valor fijo
}
return suma;
}
