Better use std::set instead of std::map

Look a bit like waste of memroy.

Pro number 1 : auto uses type deduction which simplifies life considerably.

Pro number 2: auto forces you to initialize a variable hence you can’t forget doing that. Statement “auto x” is illegal.

Pr0 number 3: If you change datatypes afterwards (eg int to float), you need to change it less times

Con: Referring to pro number 1 “Our virtues and our failings are inseparable” :) auto may deduce type incorrectly, but luckily it’s hard to trick it. One such case is

but what's the advantage of using "auto"??

Thanks for the explanation DarkD1 👍

and sometimes c++ gives up(std::vector <auto>)

It tells C++ to try and automatically detect the type.

Hey man! What does "auto" do??

that simple😮

Poor description.
At least give one example on how flipping occurs, for example in the given example: "0011001100", [I, 1, 10] 7th bit is 1 when I would flip that it would be 0 but answer expects me 1.

Nice and clean
