java - Converting this line of code to a for loop -

so in java, i'm trying execute: num [0]=list.get(2); num [1]=list.get(4); num [2]=list.get(6); num [3]=list.get(8); i have arraylist of integers called list , want put values in number indices starting @ 2 array of integers called num in indices 0,1,2,3,etc. problem is, i'm trying within loop i'm not sure how go it. here have: for (int i=0; i<list.size()-2; i++){ num[i] = list.get(i+2); } my problem here is, after incrementing i, arraylist goes next index instead of every other index. i've tried multiple variations of loop keep coming same problem. this should it: int max = list.size()/2; if(list.size()%2==0) max-=1; // prevents indexoutofbounds list lengths (int i=0; i<max; i++){ num[i] = list.get(i*2 + 2); }

git - Visual Studio: Pushed solution to Team Services but won't push submodule -

Image
i'm having trouble connecting team code because submodule did not pushed during initial commit. shows change needs committed, when try commit it, error says "fatal: unexpected sequence in commit output." i've looked everywhere , seems i'm 1 having problem. of course, team cannot pull code because not contain submodule. has else experienced before? for adding submodule git repo , push remote , should use these commands: git submodule add <sub repo url> git commit git push then submodule pushed remote repo successfully. to pull changes remote (including submodules) other developers: git pull git submodule update --recursive to clone remote repo submodules : git clone <url> --recursive or select recursively clone submodules using vs clone repo.

DynamoDB: How to fetch single item where attribute value is not in a given list of values? -

i understand query might inefficient since can involve full table scan in worst case, need fetch single item @ time. for example, have table containing values this: { id: 'bc63a25e-b92b-483e-9ad3-ad6d474dfae2', domain: 'xyz.com', template_url: `https://s3.us-east-2.amazonaws.com/bucket/some-random-url.html`, data_elements: { message_link: 'http://www.google.com' zodiac_sign: 'scorpio' } } i have gsi domain hash key. want fetch items table: where domain == 'xyz.com' , id not in <a list of ids> limit 1; how can achieve type of query ? checked documentation , see there in operator not find not in operator. i had same issue, , don't think can. need use key 'get' method , 'scan' method. alternative (i think) fetch items , string comparison on each , everyone. don't think need mention how incredibly expensive be. as mentioned, had deal same issue , ended changing data structure...
