Please write in C++ and briefly explain. Thank you.

first string = "ACCT" Example: ACCT second string = "ACCG" ACCG In this example, there are 3 matching characters and 1 mismatch, so hamming-distance-1 The similarity score for two sequences is then calculated as follows: similarity-score = (string length-hamming-distance) / string length similarity-score = (4-1)/4-3/4-075 Two sequences with a high similarity score are more similar than two sequences with a lower similarity score. The two strings must always be the same length when calculating a Hamming distance
