Plz send your code here, so that I could check it

please see my code its on the editor

#include<bits/stdc++.h> using namespace std; int main() { int N; int M; cin>>N; cin>>M; if(1<= M <= 10 && 1<= N<= 10){ int arr[M][N]; for(int i = 0 ; i< M ; i++){ for(int j = 0 ; j < N ; j++){ cin>>arr[i][j]; } } int flag = 0; for(int j = 0 ; j < N; j++){ if(flag == 0){ for(int i = 0 ; i < M ; i++){ cout<<arr[i][j]<<", ā€œ; flag = 1; } } else{ for(int i = M - 1; i >= 0 ; iā€“){ cout<<arr[i][j]<<ā€, ā€œ; flag = 0; } } } cout<<ā€ END"; } else{ return 0; } }

Rachit, its really difficult to understand your code like this, plz save on ide and then send it here
