Given the maximum possible area of the right angle triangle for a fixed length of hypotenuse. The task is to find the length of hypotenuse.

Note: If the answer comes in Decimal, find it's Floor value.

Example 1:

Input:N = 25Output:10Explanation:For a maximum area of 25 square Units
of a Right-angled Triangle,
the length of it's Hypotenuse is 10.

Example 2:

Input:N = 21Output:9Explanation:For a maximum area of 21 square Units
of a Right-angled Triangle, the
length of it's Hypotenuse is 9.165 = 9.

Your Task:
You don't need to read input or print anything. Your task is to complete the function getHypotenuse() which takes an Integer N as input and returns the answer.
