Last case I moved all 0 in the end, and this one is to delete the zero:

class Solution {
public:
    int removeElement(vector<int>& nums, int val) {
        int n = nums.size();
        int j = 0;

        for(int i = 0; i < n; i++){

            if (nums[i] != val){
                nums[j] = nums[i];
                j++;
            }
        }

        for(int i = j; i < n; i++){
            nums[i] = 1;
        }

       
    }
};

 The only one I need to do is to rey=turn j

class Solution {
public:
    int removeElement(vector<int>& nums, int val) {
        int n = nums.size();
        int j = 0;

        for(int i = 0; i < n; i++){

            if (nums[i] != val){
                nums[j] = nums[i];
                j++;
            }
        }

        for(int i = j; i < n; i++){
            nums[i] = 1;
        }

        return j;
    }
};
