Maybe I just misunderstand what a pangram is. Can a pangram contain numbers and be a pangram - google seach material.

Would this not break on the numbers? if the string is "The1 Fox2"etc in a way that contained the entire .ascii a-z, but also included numbers would this not return true even though its not a pangram?

A better example on how the force is applied would be nice.

Needs random tests

This was a nice one. Thanks!

There is O(1) solution for two coins (with O(c) preparations, where c is value of greater coin).
It also exists for three coins, but that's where calculations start getting... complicated.

I do not see any point in Simulator class, it could be just a single function, which gets ship, events and time as parameters. Class distracts a little from main goal.

I made another update to finally fix the last remanants of this testing error.

I think that test fixtures for this kata are not strict enough. Correct me if I am wrong, but this solution is not checking if the final result is longer than 140, but the entry string, so it might filter out strings that are over 140 characters, but would generate hashtags that are shorter than 140 chars.

That's one option. Would still be nice to be able to turn off features :-)

Ability to easily unsubscribe from THIS thread. I have posted my feature request and now I'm getting emails every time somebody adds to this discussion, even if it is not releated to my request.
If it's already possible then please tell me how. Thank you in advance.

Could require intermediate results maybe?

Take some of the math interpreter katas. These would be no fun at all, if "eval" (or "Function") was an accepted solution. Sometimes some particular feature is not allowed by the kata and is/should be turned off.

Fixed.
