    public class Solution {
        public int RemoveElement(int[] nums, int val) {
            return nums.Length;

    Leetcode Submission Result: Wrong Answer
    Input: [4,5]
    Output: [4]
    Expected: [5]

    it works as expected [5].

    Therefore from the caller side it has no idea what's being changed in the function.
