Factorial Trailing Zeros Problem
You are provided with a positive integer N. Your goal is to determine the smallest number whose factorial has at least N trailing zeros.
Example:
Input:
N = 1
Output:
5
Explanation:
The factorial of 5 (5!) is 120, which contains at least 1 trailing zero, making it the smallest such number.
Input:
The first line contains an integer 'T' indicating the number of test cases. Each test case consists of a single integer 'N' representing the required number of trailing zeros.
Output:
For each test case, output the smallest number whose factorial contains at least N trailing zeros. Each result should be on a new line.
Constraints:
- 1 <= T <= 10
- 0 <= N <= 108
- Time Limit: 1 sec
Note:
You do not need to print anything. Just compute and return the result.
