 # PTMSSNG - code problem

During this July Long Challenge, I faced a very weird issue about this PTMSSNG question. I understood the question very well came up with the solution to the number occurring an odd number of times in each x and y coordinate array. I used the bitwise xor operation to find the number occurring an odd number of times.

Here’s the code in C++

``````#include <iostream>

using namespace std;

int main()
{
int T, N;
long long x, y, xm, ym, len;

cin >> T;

while(T-- > 0)
{
cin >> N;
N = 4*N - 1;

xm = ym = 0L;

while(N-- > 0)
{
cin >> x >> y;
xm = xm ^ x;
ym = ym ^ y;
}

cout << xm << " " << ym;
}
return 0;
}
``````

Result:

Now here’s exactly the same code in JAVA.

``````import java.util.Scanner;
class Test
{
public static void main(String[] args)
{
int T, N;
Scanner in = new Scanner(System.in);
T = in.nextInt();

while(T-- > 0)
{
N = in.nextInt();
N = 4*N - 1;
long X = 0;
long Y = 0;

while(N-- > 0)
{
X =  X ^ in.nextLong();
Y =  Y ^ in.nextLong();
}

System.out.println(X + " " + Y);
}
}
}
``````

Result:

Question is why language made a difference here?? Is there some difference between the xor operation between the two languages?

Thanks!

You just forgot the ‘\n’ or endl in your C++ code. It’s nothing about language.

You are not printing new line

You forgot to add next line at the end of the answer in c++ solution.

Ahh…! what a pain!
Thanks, I was really starting to like JAVA more than C++ you forgot new line in C++.
