how to eliminate empty arrays from an array of arrays in ruby? -

-

i have array of arrays. want eliminate empty arrays.

iam using reject!(&:empty?) method. giving me unexpected results.

2.2.2 :306 >   array = ["yes","yes","yes"]  => ["yes", "yes", "yes"]  2.2.2 :307 > array.split("no")  => [["yes", "yes", "yes"]]  2.2.2 :308 > array.split("no").reject!(&:empty?)  => nil  2.2.2 :309 > array_with_no = ["yes","yes","yes","no"]  => ["yes", "yes", "yes", "no"]  2.2.2 :310 > array_with_no.split("no")  => [["yes", "yes", "yes"], []]  2.2.2 :311 > array.split("no").reject!(&:empty?)  => nil  2.2.2 :312 > array_with_no.split("no").reject!(&:empty?)  => [["yes", "yes", "yes"]]  2.2.2 :313 >

i want result when there no empty array eliminate, should return same array instead of returning nil

you want reject instead of reject! (the !-version modifies array in-place , returns true or nil depending on if changes array made or not)

documentation on methods do

Deploying Qt Application on Android is really slow? -

-
as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
