Remove Element

Question

Given an integer array nums and an integer val, remove all occurrences of val in nums in-place. The order of the elements may be changed. Then return the number of elements in nums which are not equal to val.

Input: nums = [3,2,2,3], val = 3

Output: 2, nums = [2,2,,]

Input: nums = [0,1,2,2,3,0,4,2], val = 2

Output: 5, nums = [0,1,4,0,3,,,_]

class Solution {
    public int removeElement(int[] nums, int val) {
        int res=0;
        for(int i=0;i<nums.length;i++){
            if(nums[i]!=val){
             nums[res]=nums[i];
                res++;
            }
        }
       return res;
        
    }
}
