c++ bit array challenge - Tahh - Apr 6, 2020
I'd like to know if anyone has solved this problem on this site.
https://www.hackerrank.com/challenges/bitset-1/problem
Even all the submitted answers cause compile error and it doesn't seem like anyone has ever gotten it write.

A few points on terms and operators..
Quote:S (modulo 2^31)
What is the ^ in this case? Is it raise to the power or is it XOR?
How are the parentheses significant?
What is the equivalent operation in C\C++ for modulo?
Just want to make sure the terms are understood before I look at this problem.

Just grabbed the first solution from the site, compiles fine on my system?

For me when I try to compile it on the site it says the solution doesn't work.

I don't know how to interpret the problem, too advanced for me.

I believe, considering it is a constraint to the problem, it is not XOR but rather combinatorics towards the amnt of possible solutions.
