String[] str1 =new String[n];
String[] str2 =new String[n];
for(int i=0;i<n;i++) {
str1[i]=s.nextLine();
str2[i]=s.nextLine();
}
for(int i=0 ;i<n ;i++) {
int len=str1[i].length();
for(int j=0 ;j <len ;j++) {
char ch1=str1[i].charAt(j);
char ch2=str2[i].charAt(j);
if(ch1==ch2) {
System.out.print(“0”);
}else {
System.out.print(“1”);
}
}
}
}

@sameeksha,

Don’t use s.nextLine(); for input. Instead use s.next(); because the inputs are given in a single line. Also, after printing the output of a test case print, the next output in the next line. So add a println statement after that. I have attached the corrected code below.
