Need help writing the code for the following problem

Part 2 Count the matches of a sequence to a genome int countMatches(string genome, string sequence1, float min_score) The countMatches function takes three parameters, a string containing the genome to search, a string containing the sequence to find, and a floating point value containing the minimum similarity score that will be considered a match The function does the following: The function should find all the positions of the genome where the genome's substring matches sequence1 with a similarity greater than or equal to the min_score. . The function shouduthe countof thubfuch poslions t faund. Example: n matches countMatches("cCGCCGCCGA", "CGC", 0.60) Matching genome to CGC at 0.60 similarity. The sequence CGC matches 100% at position 1 and 4. Position 7 matches at 67%, still above the threshold. Therefore, the value returned by the function would be 3
