Name (please type legibly, ideally in block letters): ______________________________________________________________________
1. Write down a code that, given two arrays a and b of the same size, returns their component-wise difference, i.e., an array c for which c[0]=a[0]-b[0], c[1]=a[1]-b[1], ...
for (int i = 0; i < a.length; i++) c[i] = a[i] - b[i];2. Write down a method that, given an array a, returns the number of all positive elements of this array.
public static int numPositive (int[] a){
int number = 0;
for (int i = 0; i < a.length; i++)
if (a[i]>0) number++;
return number;
}
