Textbook Question
Chapter 11, Problem 23P
In Sec. 9.2.1, we determined the number of operations required for Gauss elimination without partial pivoting. Make a similar determination for the Thomas algorithm (Fig. 11.2). Develop a plot of operations versus n (from 2 to 20) for both techniques.

We have designed a divide-and-conquer algorithm that runs on an input of size n. This algorithm works by spending O(1) time splitting the problem in half, then does a recursive call on each half, then spends O(n2 ) time combining the solutions to the recursive calls. On small inputs, the algorithm takes a constant amount of time. We want to see how long this algorithm takes, in terms of n to perform the task.
(a) First, write a recurrence relation that corresponds to the time-complexity of the above divide and conquer algorithm.
(b) Then, solve the relation to come with the worst-case time taken for the algorithm.
Please show all work in depth.
