The Monkey has swung home to find his tree all in pieces.
He likes order and scoops up all his 'tree-parts' and sets them out in 3 groups.
The Monkey's 3 nested lists:
STEP = [['S', '1', 'B', '3'], ['S', '3', 'B', '11'], ['S', '5', 'B', '12'], ['S', '4', 'B', '13'], ['S', '2', 'B', '14']]

Pattern string
The pattern string follows this grammar:
pattern_string := SAFE_CHAR | ASCII_RANGE pattern_string*
CHAR := any ASCII ch...

Set Up: For two sets \$A,B\$, we say \$A \subseteq B\$ if every element in \$A\$ is also in \$B\$.
Another way of saying this, is that we can order the elements of \$A,B\$ into two lists \$L_A,L_B\$, such that \$L_A[i] = L_B[i]\$ where \$i\$ ranges over the indices of \$L_A\$.
We proceed to ex...
I am currently solving a Haskell problem where the question asks me to use as few tokens as possible. As a function used between backticks (including the backticks) marks counts as one token, it would make my code very efficent to have a pow function I can use.
This is an extract of my code, and...
