In our analysis of the select algorithm for a block size of 5, we compared the median of the medians with every other element in the input array to partition it. However, that led to more comparisons than we should have done. We could reduce it since we know that at least 3n/10 elements are less than or equal to the median of the medians and similar number of elements is at least greater than or equal to the median of the medians. Obtain a new upper bound on the worst-case number of comparisons using this piece of information. What is the value of the constant?

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
