Using the function that returns the number of times an item occurs in an array, define a function that when passed two arrays, returns true if they contain the exact same items, even if in a different order, false otherwise. Return false if either array is null.

int count(int[] data, int item) {
  int result = 0;
  for(int i=0; i < data.length; i++) {
    if(data[i] == item) {
      result++;
    }
  }
  return result;
}
