Procedure TreeSearch (x, K) i if (x = NIL) or (K = x. key) then 2 return (x); 3 else if (K < x. key) then 4 | TreeSearch (x. left, K); 5 else 6 TreeSearch (x. right, K); 7 endConsider a binary search tree where each tree node v has a field v. sum which stores the sum of all the keys in the subtree rooted at v.

We wish to add an operation SumLE(K) to this binary search tree which returns the sum of all the keys in the tree whose values are less than or equal to K.

(a) Describe an algorithm, SumLE(K), which returns the sum of all the keys in the tree whose values are less than or equal to K. Give pseudo-code for your algorithm. Your algorithm should take the same time as operation TreeSearch from slide 7.12.

(b) Explain why your algorithm is correct, i. e., why it returns the sum of all the keys whose values are less than or equal to K.

(c) Analyze the running time of your algorithm in terms of the size n and height h of the binary search tree.

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
