Leetcode Move Zeroes problem solution

In this Leetcode Move Zeroes problem solution we have given an integer array nums, move all 0's to the end of it while maintaining the relative order of the non-zero elements.

Problem solution in Python.

class Solution:
    def moveZeroes(self, nums: List[int]) -> None:
        """
        Do not return anything, modify nums in-place instead.
        """
        for i in range(len(nums)):
            if(nums[i]==0):
                nums.remove(nums[i])
                nums.append(0)
            else:
                continue

Problem solution in Java.

class Solution {
    public void moveZeroes(int[] nums) {
        int idx = 0;
        for (int i = 0; i < nums.length; i++) {
            if (nums[i] != 0) {
                nums[idx] = nums[i];
                idx++;
            }
        }
        for (; idx < nums.length; idx++) {
            nums[idx] = 0;
        }
    }
}

Problem solution in C++.

class Solution {
public:
    void moveZeroes(vector<int>& nums) {
        
        int n = nums.size();
        int l = 0, r = 0;
       while(r < n && l < n) {
           while(l < n - 1 && nums[l] != 0) {
               ++l;
           }
            while(r < n- 1 && (r <= l || nums[r] == 0)) {
               ++r;
           }
           swap(nums[l++], nums[r++]);
       }
    }
};

Problem solution in C.

void moveZeroes(int* nums, int numsSize){
    int p1 = 0, p2 = 0;
    
    while(p2 < numsSize){
        while(p2 < numsSize && nums[p2] == 0) p2++;
        if(p2 < numsSize && p1 < p2){
            nums[p1] = nums[p2];
            nums[p2] = 0;
        }
        p1++;
        p2++;
    }
}
