Question

[ptoledor]

for(int i=0; i<nc; i++){
    if(**nc-1 == i** || curSum+coins[i] < coins[i+1]){
        curSum += coins[i];
        res++;
    }
}   
cout << res << endl;

}

whats the logic behing "nc-1 == i"
thanks

it's simply checking the last item of the vector/array.

thanks a lot, I was stuck on why you always add a coin in the end.
