We learn how to count the number of bits to be toggled - flipped to convert input variable A to B using Bit Manipulations in C/C++. This is a common interview question for embedded/software/firmware roles. This concept is also known as Hamming distance between two binary numbers.
We learn an application of this concept, where we use it for Error Handling mechanisms. We also gain a new perspective on XOR operations between numbers which will be helpful for our upcoming episodes to solve challenging XOR problems.
