Poker Hand Rankings - Poker Basics - Poker Hands what beats what
For a homework assignment I was given a Card class that has enumerated types for the Rank and Suit.
I am required to compare two poker hands each hand is an ArrayList of 5 cards and decide the winner.
The isStraight function is really bothering me, because I have to start over the count after the Ace.
For example, QUEEN, KING, ACE, TWO, THREE Is still considered a straight.
What is the best way to code this functionality?
According to those rules not yours I've implemented something similar can a straight in poker wrap around />Basically you sort the array and walk it, making sure the current card is one higher than the previous.
If it is you return true and if it isn't you continue with the normal straight can a straight in poker wrap around />This should set you in the right direction.
Then add together all the cards call that result 'Sum'.
This tests required for this approach should be implementable quickly with a minimal amount can a straight in poker wrap around branching.
You could write a fancy algorithm to return true despite the number of possible cards but if you realize there are only 10 valid combinations on a sorted hand, you could just look for these: 2-6, 3-7, 4-8, 5-9, 6-T, 7-J, 8-Q, 9-K, T-A, 2-5,A This is the least error prone and readable answer given that Aces play a dual role — Dec 19 '11 at 4:36 Since there's only 5 cards in you list, you could sort it and determine the difference between 2 consecutive cards.
If it contains an ace, you need to consider it as a low card too.
I'd argue that given that definition of Click here, that straights can only poker new tour hostess world with a max of ACE.
If ACE can be high or low then go with what SHS answered.
With an inner loop it's pretty trivial, the challenge would be to do it without an inner loop.
Also, it depends on if you understood your teacher or your teacher misunderstood or misrepresented the rules of the game.
If you hit a duplicate, it's not a straight, and when you are done, you should have 8 spaces in a row.
If you have less than 8 spaces in a row, it's not a straight.
All the other solutions I can come up with require an inner loop--and inner loops are one of those sloppy programming things you need to avoid whenever you can if you're going to ever be a respectable programmer.
Edited again to replace 1 for ace with 14 after re-reading the question Oh, when you say "8 spaces in a row", I guess that's where you're allowing it to wrap; is can a straight in poker wrap around it?
This avoids having to sort.
You can add the ace twice once as a 1 the other times as a king or you can special case the starting situation by checking if the ace bit is set before checking if the 2 is set.
You can build a big look up table if speed matters.
zynga poker email login approach also cleaning scales to find can a straight in poker wrap around rest of the hands flushes, 2 pair, full houses, trips, and so on.
It also makes it easy to figure out if a given straight is higher than another.
Bitfields tend to require a read+write instead of just a write.
Dude, you should re-evaluate your programming priorities.
Readability before all others, optimization last, etc.
You turn all the hand evaluation into a half dozen table look ups.
I find the resulting code easier to use in a poker program but ymmv.
If your interest in this program a google will run up a bunch of fast one.
I know setting a single bit is less efficient than writing a byte to an array, but maybe you're thinking of something else.
I work with them all the time processing video streamsit's not like I'm afraid or anything, just a bad solution unless necessary.
But you don't set a single bit.
You set all the bits in 1 register for all the cards and then write out that register.
Most of the speed is from avoiding having to do a sort and being able to tell if something is a straight with some math and then 1 memory access.
With these constraints, selection sort will outperform Merge Sort and QuickSort.
If you were building the game to serve https://krimket.com/poker/casino-niagara-poker-reddit.html of users, sure, but in this context it's overkill.
Then, to check if a hand is a straight, sort the hand by rank and then check if the hand is a sublist of that list.

Between us speaking, in my opinion, it is obvious. You did not try to look in google.com?
You are not right. I suggest it to discuss.
Many thanks for the help in this question.
I am sorry, that I interrupt you, but, in my opinion, this theme is not so actual.
It is doubtful.
Bravo, what necessary phrase..., a remarkable idea
I am final, I am sorry, it not a right answer. Who else, what can prompt?
Many thanks for the help in this question, now I will not commit such error.
I apologise, but, in my opinion, you commit an error. I can defend the position. Write to me in PM.
You were visited simply with a brilliant idea
Excuse for that I interfere � At me a similar situation. Let's discuss.
Bravo, this remarkable idea is necessary just by the way
You are not right. I am assured.
You are not right. I suggest it to discuss. Write to me in PM, we will communicate.
I congratulate, what excellent answer.
And where at you logic?
I consider, that you commit an error. I can prove it. Write to me in PM, we will discuss.
I apologise, but, in my opinion, you are not right. I am assured. I can prove it. Write to me in PM, we will communicate.
I am sorry, that has interfered... At me a similar situation. I invite to discussion.
Also that we would do without your remarkable idea
To me it is not clear.
I can look for the reference to a site on which there is a lot of information on this question.
Idea excellent, it agree with you.
