Leet Code 283: Move Zeroes

Problem statement:

Given an integer array nums, move all 0's to the end of it while maintaining the relative order of the non-zero elements.

Note that you must do this in-place without making a copy of the array.

Constraints:

1 <= nums.length <= 104
-231 <= nums[i] <= 231 - 1

Soultion:

/**
 * @param {number[]} nums
 * @return {void} Do not return anything, modify nums in-place instead.
 */
var moveZeroes = function(nums) {
    let l = 0;
    let r = nums.length;
    // if(r==1)
    //     return;
    let arr = [];
    for(let i=0;i<r;i++) {
        if(nums[i] !== 0 && i!==l){
            nums[l] = nums[i];
            nums[i] = 0;
            l++;
        } else if(nums[i] !== 0 && i==l) {
            l++;
        }    
    }
    
    console.log(nums);
};
