Keep in mind that you can not sell a supply before you acquire one.

"(Service) "Provided a string, find the longest palindromic substring in. Offered input is guaranteed to be much less than 231- 1."(Solution)"Given a range of strings products and a string searchWord. We want to develop a system that recommends at a lot of 3 product names from products after each personality of searchWord is keyed in. Recommended products ought to have typical prefix with the searchWord. Return checklist of lists of the recommended products after each character of searchWord is entered."( Option)"Given a paragraph and a listing of prohibited words, return the most constant word that is not in the checklist of prohibited words. It is guaranteed there is at the very least one word that isn't prohibited, and that the answer is special. Words in the paragraph are not case-sensitive. The response remains in lowercase."( Solution )"Given a linked listing, reverse the nodes of a linked list k at once and return its customized listing. k is a favorable integer and is much less than or equivalent to the length of the linked listing. The brand-new list needs to be made by splicing with each other the nodes of the initial 2 listings. "(Remedy )"You are provided a selection of k linked-lists listings, each linked-list is sorted in ascending order. Combine all the linked-lists into one sorted linked-list and return it."(Service)"A linked checklist is provided such that each node includes an added arbitrary reminder which can aim to any type of node in the list or null.
