Problem statement :
You have been given an array which contains integer elements and randomly zeros are present in that array. Push all zeroes at the end of the array.
Input : 0 5 0 8 3 4 0 2 0 0
Output : 2 5 4 8 3 0 0 0 0 0
Input : 1 0 0 0 3 2 0 5 0 6
Output : 1 6 5 2 3 0 0 0 0 0
Time complexity : O(n).

One more !!
1 class Myclass {
2 int i = 10;
3 static {
4 new Toc ();
5 }
6 }
7
8 class Toc {
9 static {
10 System.out.print(new Myclass ().i);
11 }
12 public static void main (String... args) {
13
14 }
15
16 }
