Question:

Code format update

For the input below:

S1 = ACCGGTCGACTGCGCGGAAGCCGGCCGAA

S2 = GTCGTTCGGAATGCCGTTGCTCTGTAAA

S3 = ATTGCATTGCATGGGCGCGATGCATTTGGTTAATTCCTCG

S4 = CTTGCTTAAATGTGCA

S5 = AGTTAATAGGACCTGATACG

S6 = TCGTTAATAGGACCTGATACGGTTTACTAG

update the code to compare S1, S2, S3, S4, S5, and S6. Also, add execution time (see highlighted text and output below)

import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.util.Scanner;
