H-index problem

Problem Statement:

Calculate the researcher's h-index from an array of integer citations, where citations[i] is the number of citations a researcher obtained for their ith work.

According to the definition of h-index, a scientist has an index h if h of their n articles have at least h citations each, while the other n h papers have no more than h citations each.

In cases when h has multiple possible values, the highest value is used to determine the h-index.

Pre-requisite: Counting Sort

32 Keywords in C Programming

In this article, we will learn about all 32 keywords in C programming language and their uses.

As with other programming languages, there are words users are not allowed to use as variable names, a function name or expressions of any kind in C programming. These words are called Keywords.

Keywords are simply reserved words whose semantical meanings is already known to the compiler. If they are used outside their semantical meaning, it would result in a compilation error.

There are 32 keywords in...
