Hackerrank Calculate the Nth term Solution

Objective This challenge will help you learn the concept of recursion. A function that calls itself is known as a recursive function. The C programming language supports recursion. But while using recursion, one needs to be careful to define an exit condition from the function, otherwise it will go into

Hackerrank Bitwise Operators Solution

Objective This challenge will let you learn about bitwise operators in C. Inside the CPU, mathematical operations like addition, subtraction, multiplication and division are done in bit-level. To perform bit-level operations in C programming, bitwise operators are used which are explained below. * Bitwise AND operator & The output of bitwise
