: This publication covers a large array of subjects related to software engineering interviews, with a focus on Java.

Note that you can not offer a stock prior to you purchase one.
"(Solution) "Provided a string, discover the longest palindromic substring in. Given input is guaranteed to be much less than 231- 1."(Remedy)"Given an array of strings items and a string searchWord.
