leetcode solutions in java

this is my 2nd time working on leetcode. the versions indicate the number of submissions i made before being accepted. be cautious that usually only the last commit contains the accepted answer. other ones are either not efficient enough or not bug-free. some commit messages contain details of the bugs i made in earlier versions.
