Hello everyone!
Been trying this easy sum for quite some time. I get the output correct when I pass the testcase, but for reason unknown, i get wrong answer. any help is highly appreciated.
heres my code:

github.com

TarunKurella/temp/blob/good-sum/Main.java

import java.util.*;
import java.io.*;
import java.math.*;


public class Main {


static String mutate(String old,int k,char b){
  StringBuffer temp = new StringBuffer(old);
  temp.setCharAt(k,b);
  return temp.toString();
}

static void cross(ArrayList<String> genes,int d1,int d2,int k1,int k2){
String dna1 = genes.get(d1);
String dna2 = genes.get(d2);

String ans1 = dna1.substring(0,k1-1)+dna2.substring(k2-1);
String ans2 = dna2.substring(0,k2-1)+dna1.substring(k1);

Try this:

2
AAAAAAAAAA
GGGGGGGGGG
3
CROSS 1 2 5 5
COUNT 3 1 10
COUNT 4 1 10

What would you expect DNAs 3 and 4 to be? Check this with what the code sets them to.

And you might want to report the exceptions you catch so you can see what’s going wrong.
