var a = [1,3,6,10,-1]; function combinations(array, n) { }  combinations(a, 9) // should return... [[1], [3], [6], [-1], [1,3], [1,6], [1,-1], [3,6], [3,-1], [6, -1], [10, -1], [1,3,-1], [3,6,-1], [1,6,-1], [1,3,6,-1]]   maybe i'm missing some co...
Little challenge.    Goal (nodeJS, loop is an * interator function using "yield" strategy)  var str; var minChars = 1; var maxChars = 10; for (str of loop('abcdefghijklmnopqrstuvwxyz',minChars,maxChars)) {     console.log(str); }...
This seems sort of complex so I'll do my best to be as clear as possible.The particular function I'm looking for dynamically creates a money spent | money won chart for a game of gambling.  I have a lottery of sorts that the user can bet on....

I am trying to write an algorithm that generates all lottery combinations recursively.  Here is a none recursive variation that can be used to get C(max,6). e.g. c(7,6)    let min = 1; let max = 7; let lotteryNum = 0; let outputString = []; for (let...
My head isn't quite with me and hope somebody can assist...  Let's say I have:  1234567   I wish to generate a list of all possible combinations, the only restrictions are that:   A number can only appear once A higher number can't come b...
