/*
In this program you need to implement four methods with the following signatures:

printArr(int[] a)
add(int[] a, int[] b)
subtract(int[] a, int[] b)
negate(int[] a)

1. Method printArr(a) should print out all elements of a given int array in one line.

2. Method add(a, b) should take two int arrays (assume they have the same length) and return a new array each element of which will be the sum of the corresponding elements in a and b

3. Method subtract(a, b) is similar to add(), except it returns (a - b) array

4. Method negate(a)takes an int array and returns a new array in which every element is multiplied by -1.

public class ArrayOperations{

public static void main(String[] args){
//The main only has the testing code.
//You don't have to change it.

int [] a = { 1, 2, 3, 4, 5};
int [] b = {10, 1, 3, 5, 7};
System.out.print("a = ");
printArr(a);//Should print each element of a (in one line)
System.out.print("b = ");
printArr(b);//Should print each element of b (in one line)

int [] arr = add(a,b);
System.out.print("a + b = ");
printArr( arr );//Should print out the array a+b

System.out.print("a - b = ");
printArr(subtract(a,b));//Should print out the array a-b

System.out.print("b - a = ");
printArr(subtract(b,a));//Should print out the array b-a

System.out.print("-a = ");
printArr(negate(a));//Should print out the array -a (negative a)

}
}
