![]() Carry on as before trying the remaining letters:.Backtrack to index 0 and try the next letter:.Move on to index 1 and try each remaining letter in turn:.Start at index 0 and add the first letter:.So let's try an example - build all combinations of 2 letters from the set of 4 letters A, B, C and D: Make sense? Probably not as it turns out it's quite hard to explain recursive algorithms. Keep backtracking and trying each card until you're done. Once you've tried every card in the last place in the hand, backtrack to the last place but one and replace that card with the next one, then proceed as before. You can then remove the last card in the combination and replace it with the other remaining cards in the deck for the next set of combinations. ![]() Start with an empty combination and add cards from your full deck until you have reached the desired size. So we need some code to produce five card hand combinations from a full deck of cards.Ĭombinations can be built recursively. Before we can start evaluating five card poker hands we actually need to get some five card poker hands.
