please read carefully the texts provided 2 images. Then please answer for me especially this 2 questions: 1) try to solve the problem without using maps. can you do it with vectors? how about just sets? 2) after solving #1, compare your codes with the solution using maps. estimate the number of instructions your program will require to run on an input of n strings. Once again i want to remind the person who will answer for me please see 2 attachments with this questions. Basically its all about c++ coding about "Maps/sets".
