Solution: H-Index

Explore how to calculate a researcher's h-index through a counting sort approach that optimizes sorting and searching. This lesson guides you step-by-step to implement an O(n) time complexity solution, helping you understand algorithmic optimizations for coding interviews.

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 ...
