Redwolf Programs

In what way?

ChartZ Belatedly

@Wasif You need spaces between each "term". This searches for anything containing "Deadfish~", "hello" and "world", whereas this searches answers to hello-world challenges with "deadfish~" in them

(also, it's all case-insensitive)

You can also limit the search to the answers of one specific question

Why?

ChartZ Belatedly

IIRC the way it works is that each command has up to 9 different "commands". You provide a number of "sample" input, output pairs and it runs all possible programs (by varying the commands used) and chooses the one that has the best match to the samples

Of course, any program with n commands has a time complexity of O(9^n)
