+/**
+4. Move all zeroes to end of array 
+Easy Accuracy: 51.81% Submissions: 10335 Points: 2
+Given an array arr[] of N positive integers. Push all the zero’s 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)
+
+
+Constraints:
+1 ≤ N ≤ 105
+0 ≤ arri ≤ 105
