Convert floating point to natural number
Basic Accuracy: 43.35% Submissions: 30 Points: 1

Given a positive floating point number N, the task is to find the smallest integer k, such that when we multiply k with N, we get a natural number.

Example 1:

Input: N = "30.25"
Output: 4
Explanation: 30.25 * 4 = 321, there is no
number less than 4 which can convert 30.25
into natural number.


Example 2:

Input: N = "5.5"
Output: 2
Explanation: 5.5 * 2 = 11, there is no number
less than 2 which can convert 5.5 into
natural number.


You don' need to read or print anything. Your task is to complete the function findMinMultiple() which takes N as input parameter in string format and returns the minimum k such that when we multiply it with N we get a natural number.

Expected Time Complexity:O(c) where c is constant
Expected Space Compelxity: O(1)

Constraints:
1 <= N <= 1000
