code works completely fine in case of NN array like 33, but showing some 0 values in case of NM arrays like 34 or 4*3 . Can you tell what’s wrong in this code and what changes it need.
CODE:

#include
using namespace std;
int main(){

int a[100][100];
int m,n;
cin>>m>>n;
int i,j;

for( i=0; i<m; i++){
    for(j=0; j<n; j++){
        cin>>a[i][j];
        
    }
}
int k;
for(i=0;i<=m+n-2;i++){
    for(j=0; j<m; j++){

        for(k=0; k<n; k++){
            if(j+k==i){
                if(i%2==0){

                    cout<<a[k][j]<<" ";
                }
                else{
                    cout<<a[j][k]<<" ";
                }
        
            }
        }

    }
}


return 0;

}

the solution given is clear to me, but still not able to find what’s wrong in my code.

@tanishqbatra0511
ur code will work fine only with N x N matrices… for N X M it wont work as it tries to access out of bounds indices at some places…
