Each sequence must be in a seperate line.2)Make two functions, to calculate the distance of Hamming and Levenshtein.3)Make a function that calculates the optimal alignment between two sequences.4)Write a script that calls the functions above.There is more information in the file attached.Can someone help me?Thanksattachment
