 Problem :

Given an integer array nums and an integer val, remove all occurrences of val in nums in-place. The relative order of the elements may be changed.

Input: nums = [3,2,2,3], val = 3
Output: 2, nums = [2,2]
Explanation: Your function should return k = 2, with the first two elements of nums being 2.
It does not matter what you leave beyond the returned k

Solution:

 public int removeElement(int[] nums, int val) {
        int count =0;
        int i =0;
        while(i<nums.length) {
            if(nums[i] != val) {
                nums[count++] = nums[i];
            }
            ++i;
        }
        return count;
    }
