If you were only allowed to finish at many one transaction(i.e., purchase one and offer one share of the supply), layout an algorithm to discover the optimum profit. Note that you can not sell a stock before you purchase one.

"(Service) "Offered a string, find the longest palindromic substring in. Offered input is assured to be much less than 231- 1."(Option)"Given a variety of strings products and a string searchWord.
