So given input = [1, 2, 3] and k=2 this would return:  1 2 1 3 2 1 2 3 3 1 3 2   This is the closest to what I am looking for, but not quite: http://algorithms.tutorialhorizon.com/print-all-combinations-of-subset-of-size-k-from-given-array/    functi...
I'm writing something that takes a block of text and breaks it down into possible database queries that could be used to find similar blocks of text. (something similar to the "similar questions" list being generated while I type this) Th...
Please note: the linked question, "How can I create every combination possible for the contents of two arrays?" does not solve this particular question. The persons that labeled that did not fully understand this specific permutation and requ...
I was reading this question, which describes the following problem statement:     You are given two ints: N and K. Lun the dog is interested in strings that satisfy the following conditions:         The string has exactly N characters, each of which...
I solved the following leetCode problem with some code :   You have d dice, and each die has f faces numbered 1, 2, ..., f.  Return the number of possible ways modulo 10^9 + 7 to roll the dice so the sum of the face up numbers equals t.    I made two...
I am trying to make a 5x5 table that will have the numbers 1-5 random put in the rows/columns. But they need to have all different numbers for each row and column.  ex: 12345 54123 41532 35214 23451  The code I currently have is very long so I will g...
I need an algorithm that will generate 2 lists of 3 characters taken from a list of 6. For example I have an array containing [a,b,c,d,e,f] and I want to create combinations such as [a,b,c][d,e,f].   I need to get all the possible combinations of 2 t...
My question is similar to THIS question that hasn't been answered yet.  How can I make my code (or any javascript code that might be suggested?) find all possible solutions of a known string length with multiple missing characters in variation wi...
If I have n balls and k containers then this -> ( (n+k-1)! / n!(k-1)! ) will work out how many combinations there are.  I am having difficulty changing this to produce a list of all combinations in javascript.  In a function taking an array of bal...
Lets say that I have a JSON file as such:   { "item1":{"time":"00:18:21"}, "item2":{"time":"00:22:22"}, "item3":{"time":"00:02:11"}, "item4":{"time":"01:34:32...
