Connected lists (10% )Search/ Type(2%)Stacks & Queues(2%) Hash tables( 2%of inquiries, least frequent )We've also detailed typical instances made use of at Amazon for these different concern kinds below.

(Solution) "Offered a binary tree, locate the optimum course sum.

Return listing of checklists of the suggested items after each character of searchWord is typed."( Service)"Given a paragraph and a listing of outlawed words, return one of the most constant word that is not in the checklist of prohibited words.
