Getting same output in console as given in test case but on submitting no test case is correct

#1

#include
using namespace std;
int main() {
int m, n;
cin>> m >> n;
int arr[m][n];

for(int i=0; i<m; i++){
	for(int j=0; j<n; j++){
		cin >> arr[i][j];
	}
}

for(int i=0; i<m; i++){
	if(i%2==0){	
		for(int j=0; j<n; j++){
			cout << arr[j][i] << ", ";		
		}		
	}
	else {
		for(int j=n-1; j>=0; j--){
			cout << arr[j][i] << ", ";
		}
	}
}
cout << "END" << endl;
return 0;

}

@manas_gautam, I rem this question is little bit wrong in m and n value so just change n to m and m to n everywhere and try submitting once else I’ll check
