Define a method/function that removes from a given array of integers all the values contained in a second array.
Examples:
int[] integerList = new int[]{ 1, 2, 2, 3, 1, 2, 3, 4 }
int[] valuesList = new int[]{ 1, 3 }
Kata.Remove(integerList, valuesList) == new int[]{ 2, 2, 4 } // --> true
int[] integerList = new int[]{ 1, 1, 2, 3, 1, 2, 3, 4, 4, 3 ,5, 6, 7, 2, 8 }
int[] valuesList = new int[]{ 1, 3, 4, 2 }
Kata.Remove(integerList, valuesList) == new int[]{ 5, 6 ,7 ,8 } // --> true
int[] integerList = new int[]{ 8, 2, 7, 2, 3, 4, 6, 5, 4, 4, 1, 2 , 3 }
int[] valuesList = new int[]{ 2, 4, 3 }
Kata.Remove(integerList, valuesList) == new int[]{ 8, 7, 6, 5, 1 } // --> true

List<Integer> list= Arrays.stream(valuesList).boxed().collect(Collectors.toList());
return Arrays.stream(integerList).filter(i->!list.contains(i)).toArray();
