std::inclusive_scan doesn't compile on CF

Revision en1, by Savior-of-Cross, 2021-09-01 11:37:50

Not sure if this has been mentioned before, but the following code involving std::inclusive_scan doesn't compile on CF on both "GNU G++17 7.3.0" and "GNU G++17 9.2.0 (64bit, msys 2)". This function is part of the C++17 standard, according to the reference, so it should compile on both versions (and it does compile locally).

inclusive_scan

#include <bits/stdc++.h>
using namespace std;

int main(){
	vector<int> a{0, 1, 2, 3, 4, 5};
	vector<long long> pref{0};
	inclusive_scan(a.begin(), a.end(), back_inserter(pref), plus<>(), 0LL);
	return 0;
}

std::exclusive_scan doesn't compile on CF as well.

exclusive_scan

#include <bits/stdc++.h>
using namespace std;

int main(){
	vector<int> a{0, 1, 2, 3, 4, 5};
	vector<long long> pref{0};
	exclusive_scan(a.begin(), a.end(), back_inserter(pref), 0LL, plus<>());
	return 0;
}
