Arrays: move zeros to the left Given an integer array, move all elements that are 0 to the left while maintaining the order of other elements in the array. The array has to be modified in-place.

Example:

Given - [1, 10, 20, 0, 59, 63, 0, 88, 0]

Result - [0, 0, 0, 1, 10, 20, 59, 63, 88]

moveZerosToLeft,js

function moveZerosToLeft(arr) {
    
    let vaccantIndex = undefined;
    let zerors = [];

    for(let i = 0; i < arr.length; i++) {
        let curr = arr[i];

        if (curr === 0) {
            for (j = i; j >= 0; j--) {
                if (arr[j - 1] && (curr < arr[j - 1])) {
                    let interim = arr[j - 1];
                    arr[j - 1] = curr;
                    arr[j] = interim;
                }
            }   
        }
    }

    return arr;
