(d)(1)The worst case time complexity of A is n^2 (This is a false
statement).Because worst case analysis gives the maximum number of
operations assuming that the input is in the worst possible
state.Running time of an Algorithm always represented using
asymptotic notation which describes the limiting behavior of a
function.
(2)A is O(n^2)(This is a True statement) Running time of an Algorithm always represented using asymptotic notation which describes the limiting behavior of a function.

Suppose the following is a divide-and-conquer algorithm for some problem. "Make the input of size n into 3 subproblems of sizes n/2 , n/4 , n/8 , respectively with O(n) time; Recursively call on these subproblems; and then combine the results in O(n) time. The recursive call returns when the problems become of size 1 and the time in this case is constant." (a) Let T(n) denote the worst-case running time of this approach on the problem of size n....

(a) Design an algorithm that reveals some secret integer number from the set {1, 2, ... , n} by guessing random numbers within the given range until the secret number has been guessed. Numbers should be replaced after being guessed such that it is possible to guess 2 and then 2 again, assuming 2 is in the given range. The algorithm should return both the secret number as well as the number of guesses taken. (b) If possible, calculate the...

For each algorithm, give a reasonable big-O bound on its worst-case running time. Omit unnecessary terms and constants in your bound, for example, don't say O(2n22n 1), say O(n2). (In most cases, these aren't the best possible algorithms for each task!) Briefly explain your reasoning in each case.

Exercise 1 Use Top-Down Design to “design” a set of instructions to write an algorithm for “travel arrangement”. For example, at a high level of abstraction, the algorithm for “travel arrangement” is: book a hotel buy a plane ticket rent a car Using the principle of stepwise refinement, write more detailed pseudocode for each of these three steps at a lower level of abstraction.
