Consider a sample space S consisting of all perfect squares starting from 1, 4, 9 and so on. You are given a number N, you have to output the number of integers less than N in the sample space S.
Example 1:
Input :N = 9Output:2Explanation:1 and 4 are the only Perfect Squares
less than 9. So, the Output is 2.
Example 2:
Input :N = 3Output:1Explanation:1 is the only Perfect Square
less than 3. So, the Output is 1.
Your Task:
You don't need to read input or print anything. Your task is to complete the function countSquares() which takes an Integer N as input and returns the answer.
Expected Time Complexity: O(sqrt(N)) Expected Auxiliary Space: O(1)

Avoid using static/global variables in your code as your code is tested
against multiple test cases and these tend to retain their previous values.
Passing the Sample/Custom Test cases does not guarantee the correctness of code.
On submission, your code is tested against multiple test cases consisting of all
possible corner cases and stress constraints.
You can access the hints to get an idea about what is expected of you as well as
