I get the following error
error: no match for ‘operator []’ (operand types are ‘std :: list>’ and ‘int’)

if you have any ideas, thank you in advance

Answer 1

The problem is that std::list is a linked list and as such, normally you cannot access indexed element (not in constant time anyway).

I believe what you wanted to use was std::vector instead.
