this question has answer here: generating permutations of given string 41 answers i know how create permutation of given string in recursive way. lets string = "abcdefghijklmnopqrstxyz"; . i generate string of length 5 (for example) a using recursion , meaning: aaaaa aaaab aaaba aaaca zabfg thanks in advance. first, store unique characters using hashmap or so, transfer them list, call chars, ease of use. your recursive method building on string. when string reaches length 5, done, , want keep it. can return string or store in global list. in case, assume list called permutations. void generatepermutation(string current) { if (current.length == 5) { permutations.add(current); } else { (int = 0; < chars.size(); i++) { generatepermutation(current + chars.get(i)); } } }

i no means guru javascript, apologies if questions sounds "beginner". why if have 3 javascript files in project, of 3 javascript files can call of other functions in other javascript files? bigger question how can stopped? example if, of these 3 hypothetical javascript files, named managerjs.js, teamajs.js , teambjs.js, don't want teamajs able access teambjs want them both able access managerjs. all scripts on page evaluated in global scope. there single shared global scope per page. you can prevent access not defining stuff in global scope. can use iife create private scope each script: // myscript.js (function() { // declared here *local* function var localvalue = 42; // expose values explicitly creating global variables // (but there other, more elaborate ways) window.globalvalue = 21; }()); only expose values want other code / scripts access. there various ways that, 1 of them revealing module pattern . see what purpose of self ex...

i have integers copied excel spreadsheet: 1 2 3 4 5 6 7 8 9 10 with formula, i'd copied somewhere else on same excel sheet. =a1:a10 doesn't helpful , reports 1 of values, a1 field. what's trick have data copied different set of fields? i've tried =text(a1:a10), =concatenate(a1:a10), rows, columns so point , laugh @ me, please tell me what's simple trick duplicate data on same exact spreadsheet! edit... work if =e4 in 1 cell followed =e5, =e6 in own cells, still need have commas between each value. example: 1,2,3,4,5,6,7,8,9,10. as see below, concatenate worked me. thanks! turns out needed comma between each entry. figured out how concatenate works , use that. works me: =concatanate(a1,",",a2,",",a3,",",a4,",",a5,",",a6,",",a7,",",a8) result: 1,2,3,4,5,6,7,8

this question has answer here: post-increment , pre-increment concept? 9 answers i can not grasp concept how these statements produce different values. far know x+=1, means x = x + 1. know x++ should equivalent x + 1. i've searched topic , found posts ask same question, posts answered stating statements/expressions same, different result due code mistake. example provide don't see how there code mistake please explain, thank you. int x = 0; x++; x should 1 @ point because x++ adds 1 x. so why if assign x 0, , proceed code "cout << x++;" value of 0 on screen?!. how x++ become 0 if x++ equal x+1 , if x 0 1+0=1? i've been told due ++ being put after x, why matter if dealing addition 1 + 0 same 0 + 1? cout << x++; outputs value of x before increment using postfix increment operator. cout << ++x; expect.
