Move all zeroes to end of array

gistfile1.java

// Function which pushes all zeros to end of an array.
void pushZerosToEnd(int arr[], int n)
{
    int count = 0;  // Count of non-zero elements
 
    // Traverse the array. If element encountered is non-zero, then
    // replace the element at index 'count' with this element
    for (int i = 0; i < n; i++)
        if (arr[i] != 0)
            arr[count++] = arr[i]; // here count is incremented
 
    // Now all non-zero elements have been shifted to front and 'count' is
    // set as index of first 0. Make all elements 0 from count to end.
    while (count < n)
        arr[count++] = 0;
