Creating combinations using Excel -


i wondering if there function, or combination of functions (maybe requires vba) in excel me solve following problem:

there 8 people in group. need figure out , display of possible, non-repeating combinations created when 4 people selected out of 8. order of selected individuals isn’t important. need find of unique combinations.

for example: 8 people bob, carol, ted, alice, reed, sue, johnny, ben (cells a1 through a8 each contain 1 of names).

one combination bob, ted, reed, johnny. problem order of names isn’t important meaning bob, ted, reed, johnny same ted, bob, johnny, reed. combination of 4 people counts 1 instance.

i’m not trying figure out how many combinations possible. need see possible combinations.

i built binary evaluator:

public sub debugallcombinations(lpicksize long, spossibilities string, optional sdelimiter string = ";")      dim                   long     dim j                   long     dim sbin                string     dim apossibilities()    string     dim lsum                long     dim lhitcount           long      apossibilities = split(spossibilities, sdelimiter)      = 1 2 ^ (ubound(apossibilities) + 1) - 1         lsum = 0         sbin = worksheetfunction.dec2bin(i)         j = 1 len(sbin)             lsum = lsum + clng(mid(sbin, j, 1))         next j         if lsum = lpicksize             j = 1 len(sbin)                 if mid(sbin, j, 1) = "1" debug.print apossibilities(len(sbin) - j) & sdelimiter;             next j             debug.print             lhitcount = lhitcount + 1         end if     next      debug.print lhitcount & " possibilities found"  end sub

you can use this

debugallcombinations 4, "person1;person2;person3;person4;person5;person6;person7;person8"

it debug in immediate window

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
