Solution: H-Index

Understand how to calculate the h-index of a researcher by applying a counting sort method on citation counts. This lesson guides you through building frequency arrays and using reverse accumulation to find the maximum h-index value, optimizing time complexity to O(n).

We'll cover the following...

Statement

You are given an array of integers citations, where each element citations[i] represents the number of citations received for the ithi^{th} publication of a researcher.

Your task is to find the researcher’s h-index and return the value of hh.

Note: The h-index is defined as the highest number hh such that the given researcher has published at least hh papers, each of which has been cited at least hh times.

Constraints:

  • n==n == citations.length

  • ...
