Function advent_of_code_2021::day_4::parse_card [−][src]
Expand description
This takes a string with 5 lines, each with 5 space-separated numbers, representing a 5 x 5
bingo card. A regex is used to split the numbers on a line as single digit numbers cause
there to be two spaces prefixing those numbers. Iterator::enumerate is used to track the
current co-ordinates for building the map of unmarked numbers. The row and column arrays are
initialised to 0s as no numbers have yet been marked.
