Elo ratings, treating pairs of submissions as games.
I'm using the Elo system here.
Essentially, the solution is find the best solutions in each language to each challenge, and then treat each pair of such solutions as a match between those two languages, with the winner being the shorter submiss...
This is a relatively simple question. I'm trying to golf a Snake game I've written, and I'm trying to work out if there's a way to golf the following conditional assignments which control x and y coordinates of the snake ensuring a wrap around of the play area:
if (P<0) {
P = T-1;
}
if (P>T-1) ...

\$723 = 3 \times 241\$ is a semi-prime (the product of two primes) whose prime factors include all digits from \$1\$ to \$n\$, where \$n\$ is the total number of digits between them. Another way to look at this is that the (sorted) digits in the factorisation of \$723\$ are all consecutive. The f...

This challenge is about the following version of edit distance. Say we have a cost of 1 for inserts, deletes and substitutions as usual with one exception. A substitution for a given letter x for a letter y only costs 1 the first time. Any further substitutions of x for y cost 0.
As simple exam...
