Solution: H-Index

Explore how to calculate a researcher's h-index using a counting sort approach combined with reverse accumulation to avoid full sorting. This lesson helps you understand how to build and use a frequency bucket array, iterate through citation data, and determine the highest h-index value effectively within linear time complexity constraints.

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 h ...
