Is there any way for checking a point strictly inside a convex polygon in O(1)?
I know the logarithm technique.

How can I get all divisors of a number using Pollard Rho Algorithm?
Thanks in advance.
How inclusion exclusion is related with Mobius function ? In F.Relatively Prime Powers judge solution with Mobius function.
Can anyone help me get the trick for this problem with Mobius function ?
Think any one have collection of function in a header file. How it can be use in Codeforces submission?
Thanks in advance.
#include <bits/stdc++.h>
using namespace std;
const int RANDOM = chrono::high_resolution_clock::now().time_since_epoch().count();
/*const long long RANDOM = chrono::high_resolution_clock::now().time_since_epoch().count();*/
struct HASH {
template <class T>
T operator()(T x) const {
return hash<T>{}(x ^ RANDOM );
}
};
int main(int argc, char const *argv[])
{
unordered_map<int, int, HASH> table;
/* unordered_map<long long, int, HASH> table; */
return 0;
}
I'm implementing own hash function in unordered_map and facing a problem.
If my map key is int
type I've to write const int RANDOM
If my map key is long long
type I've to write const long long RANDOM
blah blah ......
How it can be better using Template?
