C++

Write a function

bool same_elements(int a[], int b[], int size)

that checks whether two arrays have the same elements in some order, with the same multiplicities. For example,

1 4 9 16 9 7 4 9 11

and

11 1 4 9 16 9 7 4 9

would be considered identical, but

1 4 9 16 9 7 4 9 11

and

11 11 7 9 16 4 1 4 9

would not. You will probably need one or more helper functions.
