why in the second last loop…i am not able to decrement the value of each key…but this is working with maps…and not with multimaps
Multimap - Code problem
@archa_1712 That is not a valid syntax to remove from multimap.
Instead you can use .
for(auto &i:m)
{
i.second-=1;
}
Or refer to this code whichyou were doing.
why are you using ‘&’ ?
