Let i represent the number of groups of size m. Solving for i, we have. For more details see https://en.wikipedia.org/wiki/Cartesian_product, I recommend to use my open source library that can do exactly what you need: Java - Generate all combinations from multiple lists. For associative arrays you only have to do a slight modification, which is: First assign the arrays keys to a variable with array_keys(), e.g. Existence of rational points on generalized Fermat quintics. Guava provides an utility function for that: Lists.cartesianProduct. Enter a custom list Get Random Combinations. Let result be the list of your required permutations. These generate the next combination from the previous and avoid repetitions. Furthermore, I use collections and generics for more flexibility: I'm using guava library for collections creation. I posted it as none of the answers here give a clear algorithm, and I can't stand recursion. What kind of tool do I need to change my bottom bracket? getline() Function and Character Array in C++. This will not change the complexity of the algorithm, but that can still improve performance a lot. Generate all possible permutations that can be created with 1 character, which is the given array. So as you can see in the above example we now have all combinations with the length of the amount of all arrays which we have. 4 How to map a list to an element in Java? Example: Calculate the number of combinations of (69 choose 5) = 11 238 513, and multiply by (26 choose 1) = 26 for a total of 292 201 338 combinations. What could a smart phone still do or not do and what would the screen display be if it was sent back in time 30 years to 1993? We loop through all our combinations, which we already have(Starting off with one combination, an "empty combination" ($combinations = [[]];)), and for each combination we go through our next data array and combine each combination with each input data to a new combination. There are many of these for different uses. This cookie is set by GDPR Cookie Consent plugin.

Guava provides an utility function for that: Lists.cartesianProduct. They are not more efficient or anything like that. Thank you! For example, given the following lists: (pseudo code would be fine too). The fundamental principle is going to be that we need to yield one grouping at a time, because there are so many possibilities that they will never all fit into memory. If we take the possibilities, it should be.

You could implement it like this: This operation is called cartesian product. dCode retains ownership of the "Combination of Choices" source code. What are assertions in Java and when should they be used? Also, your algorithm will be able to go much further before dying from out of memory. See Gosper's hack for a nifty way to get the next choice given the current choice, which is essential if you want to implement this as an iterator that yields the next grouping on each call to next(). His example made me think he didn't care though since he said "if we add a third list of length 3 then there will be 36" which isn't necessarily true if you care about uniqueness. I'll try to answer this in parts. Not: of course, if you use this solution, you must not use the iterator to store all the instances in an ArrayList or you loose all the benefit. Then do what you have to do with this Iterable rather that the ArrayList. I still see the way I wrote above used more commonly. Can i ask why you use index /= counterSize; ? how to reverse a list with O(1) space and O(n) time? You need recursion: Let's say all your lists are in lists, which is a list of lists. Let result be the list of your required permutations. Ah you're right. Can be replaced with a List. So far I've written the following code, which works by recursively finding all possible permutations and removing any duplicates (like in the example above). Categories java Tags algorithm, cartesian-product, combinations, java, list. Let's say all your lists are in lists, which is a list of lists. How to code all possible combinations of string? Since combinations are unordered, {1,3,2} = {1,2,3} --we order them to be lexicographical. And the answer is you have to multiply the amount of every array with each other. Late to the party as usual, but here's a nicely explained example using arrays. Is there a way to use any communication without a CPU? Note: There is another way:, its concept is easier to grasp and program but it's without the optimizations of Buckles. So we can generate two list a list of values and list of keys from a Map. Given an unknown amount of lists, each with an unknown length, I need to generate a singular list with all possible unique combinations. And the answer is you have to multiply the amount of every array with each other. On the other hand, if we discard the first item, then we need to select r elements out of the remaining n 1 items.
