11349  Symmetric Matrix
the problem statement is not clear to me because i don't know what should i do when n the dimension of the matrix is even like 4.

Oh, I see: [2^32 ... 2^32] doesn't fit signed 32bit integer ([2^32...2^311]), I overlooked that. However I still get WA.
I changed this
to this
That is the only I change I need to do to use 64bit integers.
I changed this
Code: Select all
int m[110][110];
Code: Select all
long long m[110][110];
Just remove the word break from your code and you'll get AC.armansuleimenov wrote:Oh, I see: [2^32 ... 2^32] doesn't fit signed 32bit integer ([2^32...2^311]), I overlooked that. However I still get WA.

As a rule, avoid use of the keyword break when reading input. (The only exception is to detect terminal character or delimiters)
PS. Please remove your code.
Hello. I get WA with my code and i don't know why. Can you help me?
Thanks.
Code: Select all
#include <iostream>
using namespace std;
int main() {
long long M[110][110];
int T;
cin >> T;
for(int cas = 1; cas <= T; cas++) {
char a, b;
int N;
cin >> a >> b >> N;
if(N <= 0)
continue;
for(int i = 0; i < N; i++)
for(int j = 0; j < N; j++)
cin >> M[i][j];
bool sim = true;
for(int i = 0; i < N; i++) {
for(int j = 0; j < N; j++) {
if(M[i][j] != M[N1i][N1j])
sim = false;
}
}
cout << "Test #" << cas << ": ";
if(sim)
cout << "Symmetric." << endl;
else
cout << "Nonsymmetric." << endl;
}
}
wrong answer 11349
Someone please cheque my code ?

Re: 11349  Symmetric Matrix
Actually, I'm having problems with understanding the problem description,
should i cut the matrix vertically or horizontally to make the comparison to check whether it's symmetric or not ????
sorry but I'm little confused here
and thanx in advance
