Poltu gives a problem to his friend Boltu. The description is given below-

You are given an integer N. You have to calculate the number of trailing zero of 1! × 2! × 3! × 4! × 5! ×……× (N - 1)! × N!

Here,
0! = 1 and A! = A × (A - 1)!

If you don't know about trailing zero, see this.

Input

The first line contains an integer T (1 ≤ T ≤ 105), number of test case.
Every Test case contains an integer N (1 ≤ N ≤ 109).

Output

For each test case, print the case number and the result of this problem.
