the answer we get for input s1=aaa, is "aaa" from the code you gave. But actual answer is "a". Then how this can be solved? Please ignore if I'm wrong.

int n3 = gcd(n1, n2);

if(str1+str2 != str2+str1){
return "";
}
return str1.substring(0, n3);
}
public static int gcd(int n1, int n2){
while(n1%n2!=0){
int rem = n1%n2;
n1 = n2;
n2 = rem;
}
return n2;
}
}
