I am trying to solve this problem in C++ many times, but I got WA. Can anyone say the problem of my code or some Testcases which help me, please?
Here is my code:

#include <iostream>

using namespace std;

long long month[12] = {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};

int main ()
{
long ...

Can anyone tells me this samples answer :

11101110111
1101101100
1010110101
11010101011
11111101111110111111

I got WA and my code's answer is :

+000-000-00-
+00-00-0-00
+0++0-0+0+
+00-0-0-0-0-
+000000-000000-00000-

If it's not true what is the true answer? And if it's true can anyone give me ...
