I found on many books regarding bitmasks and found out it is great way of representing selections,status, sets etc. But everywhere they have used an integer or long long int to define a bitmask. But that has a max capacity of 64/128 bits. How to represent more items with bits?

in the problem Saghher And Nubian Market i am getting an awkward error. I am able to output a more optimal answer, than jury, don't know how is itiwrong (in test case 6) link to my submission. please help, am a newbie. they dont have to be consecutive, but do they have to be in order?

How to define triplet vectors. I tried {pair<int,pair<int,int>>} but push_back,sort,begin, end are not working with them. Please help.
