The Hamming distance is a measure of how similar two strings are to each other. It tells you how many characters in the two strings are different from each other. For example, if you want to know how similar two words are to each other, you can calculate their Hamming distance. If the distance is small, then the words are very similar, while a large distance means that the words are very different.
The Hamming distance between two strings is defined as the number of positions at which the corresponding symbols are different. For example, if we have the two strings "karolin" and "kathrin", their Hamming distance would be 3, because the following three positions contain different characters:
The code checks whether the input left and right strings are null or not the same length, and throws an exception if either of these conditions is true. If the strings are not null and are the same length, it converts them to lowercase and then returns the number of positions at which the characters in the two strings differ.

karolin[2] = 'r' kathrin[2] = 't' karolin[5] = 'n' kathrin[5] = 'h'
