Many algorithms in Project Euler do not follow coding styles as mentioned by @dhruvmanila here, or even the standard coding guidelines.

Notes:

• A lot of inconsistencies with the solution functions (a lot of them aren't named as "solution")
• docstring inconsistencies:

>```docstring```
vs

Description of the Problem

Given an array of citations (each citation is a non-negative integer) of a researcher, write a function to compute the researcher's h-index.

According to the definition of h-index on Wikipedia: "A scientist has index h if h of his/her N papers have at least h citations each, and the other N − h papers have no more than h citations each."

Example:
Input: citati
