Details

A puzzle is a list containing:

• a list of the row clues

• a list of the column clues

A clue is a list of integers which is the run-length encoding of just the filled spaces in the final puzzle.

e.g. list(row_clues = list(2L, 2:1, c(1L, 1L), 3L, c(1L, 1L), c(1L, 1L), 2L, c(1L, 1L), 1:2, 2L), col_clues = list(2:1, c(2L, 1L, 3L), 7L, c(1L, 3L), 2:1))

A puzzle string is a just a compact string representation of the puzzle. It consists of:

• the numbers for each clue separated by a comma

• each clue separated by a colon

• the row and column clues (in that order) separated by a dash

e.g. "2:2,1:1,1:3:1,1:1,1:2:1,1:1,2:2-2,1:2,1,3:7:1,3:2,1"
