Given an unsorted array of n English words, each at most 7 letters long. You need to find the kth smallest with respect to lexicographic ordering element in this array. Show how to do it in linear time. Reminder of lexicographic order: Words are written in English alphabet. In addition to letters of English alphabet special symbol 'space (denoted ")' is assumed to be part of alphabet. In lexicographic order:• Letters of English alphabet are ordered from first to last with space being the smallest ε < a < b < c <... .,• Given two different sequences of the same length, a1, a2, . . . , at and b1, b2, . . . , bk, the first one is smaller than the second one for the lexicographical order, if ai < bi (for the order of A), for the first i where ai and bi differ.• A word cannot start with ε, but when comparing two English words of different length with respect to lexicographic order the shorter word is padded by necessary number of ε’s at the end to have the same length as the longer word.

This assignment continues work on the online booking facility introduced at the end of chapter- 10. the work will be continued in the assignments for chapters 14 and 15 (a) assume that you will produce your online booking facility using an agile approach. i. suggest the kind of user research you would like to conduct for your product before iteration cycles begin. ii prioritize the requirements for your product according to business value, i.e which requirements are likely to provide the greatest business benefit, and sketch out the ux design work you would expect to undertake during the first four iteration cycles, i.e. cycle 0, and cycles 1 to 3. (b) using one of the mockup tools introduced above, generate a mockup of your product's landing page, as developed in the assignment for chapter-11 (c) using one of the patterns websites listed previously, identify suitable interaction patterns for elements of your product, and develop a software-based prototype that incorporates all the feedback and the results of the user experience mapping achieved at the end of chapter-11. if you do not have experience in using any of these, create a few html web pages to represent the basic structure of your website
