PROBLEM OF THE DAY : 31/05/2024 | Swap two nibbles in a byte

Welcome to the daily solving of our PROBLEM OF THE DAY with Yash Dwivedi. We will discuss the entire problem step-by-step and work towards developing an optimized solution. This will not only help you brush up on your concepts of Bit Manipulation but also build up problem-solving skills.

Given a number n, Your task is to swap the two nibbles and find the resulting number. 

A nibble is a four-bit aggregation, or half an octet. There are two nibbles in a byte. For example, the decimal number 150 is represented as 10010110 in an 8-bit byte. This byte can be divided into two nibbles: 1001 and 0110.

Example 1:

Input: n = 100
Output: 70
Explanation: 100 in binary is 01100100, two nibbles are (0110) and (0100). If we swap the two nibbles, we get 01000110 which is 70 in decimal.
