I was wondering that too, just learnt that chars can be compared.

That being said, how do they do this?

For eg, why does 3+2 = 101?

I could not believe my eyes indeed, I dunnot about 20x but I got 8x faster 265k & 288k op vs 2.3M

that's certainly one way to solve this problem LOL. nicely done!

You're right, pal. Probably most right than you think シ.

Exactly, both are between 0 and 4, you're welcome.

0<=(x||y)<=4 means that the x || y are from 0 to 4? Got it! Thanks for explaining!

Notes:

• there are 10 matches in the championship
• 0 <= x <= 4
• 0 <= y <= 4

It says "x:y", it doesn't say that they are single digit values... or I'm missing something

Given the constraints in the instructions, this code is ok

If the game won or lost with double digit count, this will fail... and Kata creator prbably should've included such tests...
