Given an array arr[] of N positive integers. Push all the zeros of the given array to the right end of the array while maitaining the order of non-zero elements.
Example 1:
Input:
N = 5
Arr[] = {3, 5, 0, 0, 4}
Output: 3 5 4 0 0
Explanation: The non-zero elements
preserve their order while the 0
elements are moved to the right.
Example 2:
Input:
N = 4
Arr[] = {0, 0, 0, 4}
Output: 4 0 0 0
Explanation: 4 is the only non-zero
element and it gets moved to the left.
Your Task:
You don't need to read input or print anything. Complete the function pushZerosToEnd() which takes the array arr[] and its size n as input parameters and modifies arr[] in-place such that all the zeroes are moved to the right.
Expected Time Complexity: O(N) Expected Auxiliary Space: O(1)

Avoid using static/global variables in your code as your code is tested
against multiple test cases and these tend to retain their previous values.
Passing the Sample/Custom Test cases does not guarantee the correctness of code.
On submission, your code is tested against multiple test cases consisting of all
possible corner cases and stress constraints.
