Hello everyone,
I have a program that needs to find straights in a hand of cards. The hand
is a string with no whitespace sorted by the cards' ranks, eg "9d10cJhQsKd".
How can I identify if that hand contains a straight with a single regex? Is
that even possible?
Is there a way to escape the regex
What's a slick way to enumerate all subarrays of length n from a master
array of length m? For example I've been enumerating all possible two
card hands from a deck of 52 cards (n=2, m<=52) using nested for loops:
for ( $i = 0 ; $i < $#deck ; $i++ ) {
for ( $j = $i+1 ; $j <= $#deck ; $j++
