let s set of n integers stored in array (not sorted). design algorithm find 10 largest integers in s (by creating separate array of length 10 storing integers). algorithm must finish in o(n) time. i thought maybe answer using count sort , adding last 10 elements new array. apparently wrong. know better way? method 1: can use findmax() algorithm find max number in o(n) , if use 10 time : 10 * o(n) =o(n) each time find max num put in new array , ignore next time use findmax(); method 2: you can use bubble 10 times: 1) modify bubble sort run outer loop @ 10 times. 2) save last 10 elements of array obtained in step 1 new array. 10 * o(n) =o(n) method 3: you can use max heap : 1) build max heap in o(n) 2) use extract max 10 times 10 maximum elements max heap 10 * o(logn) o(n) + 10 * o(logn) = o(n)

i set environment variable in httpd-vhosts.conf setenv early_var 1 i try setting special rules based on value in .htaccess <if "%{env:early_var} == '1'"> setenv test_var if_branch </if> <else> setenv test_var else_branch </else> i expect test_var environment var equal if_branch . in php var_dump(getenv('early_var')); // string '1' var_dump(getenv('test_var')); // string 'else_branch' i tried setting early_var in .htaccess above if/else, both using setenv , setenvif . else branch executed. why this? apache 2.4 without using expression i.e. if/else directives can this: # set early_var 1 setenvif host ^ early_var=1 # if early_var 1 set test_var if_branch setenvif early_var ^1$ test_var=if_branch # if early_var not 1 set test_var else_branch setenvif early_var ^(?!1$) test_var=else_branch this work older apache versions i.e. <2.4 edit: in apache config or v...

while using sourcetree renamed 2 main local branches (master , develop). however, when click on git flow icon start new feature, tells me repository needs initialized (even though has been been initialized). additionally, repository -> git flow -> initialize repository menu item greyed out. i tried putting names of branches , git flow works again! so, how rename branches , keep git flow working? shut sourcetree, , edit file .git/config (within repository) updating [gitflow "branch"] section. .git directory hidden within file explorer. the default this: [gitflow "branch"] master = master develop = develop and should change match new branch names, i.e.: [gitflow "branch"] master = yournewmasterbranchname develop = yournewdevelopbranchname then restart sourcetree

i learning python , have assignment better understanding of "class" , using "stack." the requirements follows: -define class implements stack numerical values. -cannot use built-in pop function -function push should check if value numerical -function print_stack should print values in stack, recent (on top) first -function isempty should return true if stack empty, false otherwise here work far: class stack(): def __init__(self): self.items = [] def push(self, item): self.items.append(item) def isempty(self): return (self.items == []) #can use return not self think? def print_stack(self): print self.items this first class in programming i'm sorry if understanding poor. i'm not looking outright write me. want understand how go , receive pointers on need lacking in understanding if obvious. my questions follows: 1) how can test if pushing numerical value? on first thought, use try/...
