rejecting because:

• the language version is invalid for cpp
• i fixed the issue (wrong return type in initial solution ) in another fork

that was very interesting, thanks!

Sure, my foul

This isn't possible in any current version of C#.

2^31 = 2147483648

(DateTime.MaxValue - DateTime.MinValue).TotalDays = 3652059 (less than 2^31)

cycleLength is int, which has a max value of 2147483647 (less than 2^31)

There is no possible way to pass this method values that will cause the error you describe.

c# tests give growing input? every next test is previous+newtest. last test already has 200 lines (all previous lines together)

Thanks for reply! however your answer is flaged as spoiler, so... =)

C++:

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

these fields not needed in setup

very interesting kata! 100+ lines but I did it =)

Approved.

Please use spoiler flag next time, your post was visible in the homepage.

Yours is very neat! Thank you for showing me. I changed mine following your suggestions, looks cool now IMO. But I am not sure about random(). As I understand 5 fields must be somewhere outside of it, to avoid initializing them every time I call function.
