This code is showing my output as "END" on hqackerblocks but other compilers are showing that it is correct as needed

#1

#include //
using namespace std;
int main() {
int N,M;
cin>>N>>M;
int A[N][M];
for(int i=0; i<N; i++)
for(int j=0; j<M; j++)
cin>>A[i][j];

for(int i=0; i<N; i++)
{
    if(i%2==0)
    {
        for(int j=0; j<M; j++)
        {
            cout<<A[j][i]<<", ";
        }
    }
    else{
        for(int j=M-1; j>=0; j--)
        {
            cout<<A[j][i]<<", ";
        }
    }
}
cout<<"END";
return 0;

}

Hello @AyushKumar9032,

There is logical error:
//You have to print column wise
//N is for row and M is for columns
//for(int i=0; i<N; i++)
for(int i=0; i<M; i++)
{
if(i%2==0)
{
//for(int j=0; j<M; j++)
for(int j=0; j<N; j++)
{
cout<<A[j][i]<<", “;
}
}
else{
//for(int j=M-1; j>=0; j–)
for(int j=N-1; j>=0; j–)
{
cout<<A[j][i]<<”, ";
}
}
}

Hope, this would help.
