Need help with writting this code

Part 3 - Find best matching genome for a given sequence We have a random DNA sequence, and we want to find the closest species to it. Is the DNA sequence more similar to human, mouse, or unknown'? When could this kind of comparison be useful? Suppose that the emergency room of some hospital sees a sudden and drastic increase in patients presenting witha particular set of symptoms. Doctors determine the cause to be bacterial, but without knowing the specific species involved they are unable to treat patients effectively. One way of identifying the cause is to obtain a DNA sample and compare it against known bacterial genomes. With a set of similarity scores, doctors can then make more informed decisions regarding treatment, prevention, and tracking of the disease The goal of this part of the assignment is to write functions that can be useful to determine the identity of different species of bacteria, animals, etc . By simply using the similarity score routine you implemented you can compare an unknown sequence to different genomes and figure out the identity of the unknown sample float findBestMatch(string genome, string seq) The findBestMatch function should take two string arguments and return a floating point value of the highest similarity score found for the given sequence at any position within the genome. In other words, this function should traverse the entire genome and find the highest similarity score by using similarityScore() for the comparisons between sea and each seguential substring of genome
