i dont get it at all...it looks good though. at least to me
help pls

#include<iostream>

using namespace std;

int main(){

    int m,n,a;
    cin >> m >> n;
    a=(m*n)%2;
    if(a==0) cout << "[:=[first]";
    else if(a==1) cout << "[second]:=]";
}

ok. = mark in "[second]:=]" is in the wrong place.
should be     "[second]=:]" .      O_O - embarrassed.
always something to learn.
