题目描述
Given a number N.Find the sum of fifth powers of natural numbers till N i.e. 1^{5}+2^{5}+3^{5}+..+N^{5}.
Example 1:
Input:
N=2
Output:
33
Explanation:
The sum is calculated as 1^{5}+2^{5}=1+32=33.
Example 2:
Input:
N=3
Output:
276
Explanation:
The sum is calculated as 1^{5}+2^{5}+3^{5}
=1+32+243=276.
Your Task:
You don't need to read input or print anything.Your task is to complete the function sumOfFifthPowers() which takes an integer N as input parameter and returns the sum of the fifth powers of Natural numbers till N.
