IMHO, recursive is the best solution to this problem. In fact, what you described is a homework problem for recursion, in many cases. This is pretty much a standard problem for recursion to solve. Actually, what you just described is exactly what a permutation is. Without repetition you get N! I mean you can reverse and but the size of each array should be N. What do you mean when you say 'find all combinations'? Hi Peteri want to stor every solution as described in my last post in char array. Not a great recommendation for the SCJPthat.

How many different ways are there to traverse such a graph?Censorship is the younger of two shameful sisters, the older one bears the name inquisition. This basically reduces the permutations generating problem into a graph traversal problem: given a complete graph, visit all nodes of the graph without visiting any node twice. Generating all permutations of a string of characters : The key to understanding how we can generate all permutations of a given string is to imagine the string which is essentially a set of characters as a complete graph where the nodes are the characters of the string. Essentially this is a set of all combinations of all lengths 0 to size of the set of the set. A related concept is the concept of Power Set.Ī Power Set of a set of discrete elements is the set of all subsets of elements from the original elements. We will be using the Java programming language to write the code for this. The number of possible permutations and combinations that can be generated from a set of discrete elements can be huge. Two concepts that often come up in the study of combinatorics are permutaions and combinations of a set of discrete elements. Combinatorics is a branch of mathematics that deal with counting of discrete structures. Sunday, September 9, Generating all permutations, combinations, and power set of a string or set of numbers. I am having trouble visualizing this as a tree. The combination seems not to be working correctly if the alphabets are repeated in the set. Will try to add that when I have some time. Yeah, I should have added some complexity analysis here. I was just thinking how combos looked like a k-graph problem, searched and found this post. Yes, I was never able to fully understand the permutation generation solution until I started viewing this as a graph traversal problem. I never thought of the permutations problem in terms of graph before. (c) Home > Close & Load > Close & Load To.This is so cool.

By adding a custom column with a formula referring to the first data query, Power Query will perform a Full Outer Join across the two columns resulting in all combinations.

To work with unique entries, either use the standard Excel tool Data > Remove Duplicates, or in Excel Power Query Editor, right click the data column header and click Remove Duplicates.Ĭreate separate queries for each column to be included in the combinations. In this example, Column B has two data entries per cell, which can be split using Data > Text to Columns. If you need to create all combinations of data from two columns (rather than unpivoting), normalize the data by placing each set of values in its own column. Ron Rosenfeld's answer unpivots the data as the OP indicated by the required result.

The data in column B is delimited by a space.

I think I need to use INDEX, but I am unsure on the correct syntax for this scenario. I have the following simplified data set which I need to create a unique list from and transpose the data from column B at the same time.
