(b) [5 points] Let . Tell us the value of Note that you will et o points if you just povide the ansver. In other words, you must show your reasons.
#471752
(c) [5 points] Given the size n of the input data, where n is a positive integer, we assume that a program requires the running time T1(n) = O( f(n). Derive the function f(n) .
#471753
(d) [5 points] Let n be the radius of a circle C and A(n) be the area of C. Let T2(n)=|sinθ|xlog A(n)= O(f(n) . Derive the function f(n).

2. [5 points] Consider the following function F written in a C-like pseudo-code, which takes an array A of n positive integers and an initially-empty stack S as input parameters: What is the output (returned value) of the function F for the array A= [2, 14, 4, 7, 11, 18, 10, 15, 6, 23, 12, 8]?

(1) [10 points] Please find the vertex sequence derived by DFS and BFS respectively. Note that we assume that node A is the root.
#471755
(2) [10 points] Please apply Kruskal's algorithm to drive the minimum cost spanning tree. Note that you must show your actions step by step.
