Given an unknown amount of lists, each with an unknown length, I need to generate a singular list with all possible unique combinations. I prefer your approach much better than a recursive approach, especially when larger lists are being processed. The code above will generate all the possible combinations of the given array in the form of three numbers. We want all numbers from 1 to n. We first push all numbers from 1 to k in tmp_vector and as soon as k is equal to 0, we push all numbers from tmp_vector to ans_vector. But what does this mean? re du hh It may take a while to generate large number of combinations. of EDIT 2: after reviewing the link in the answer, it turns out that Guava users can have the powerset method in com.google.common.collect.Sets. But not for 3 element pair and more.. ad To generate all combinations, the approach I took is similar to this problem. yk ee hf He has 7 years of Software Development experience in AI, Web, Database, and Desktop technologies.
