A directed graph is defined by the arrow diagram below. Based on the definitions in the zyBook, which one of the following accurately describes the sequence of vertices 2,3,1,3,4{“version”:”1.1″,”math”:”2,3,1,3,4″} with respect to the graph?

An algorithm contains a nested for-loop.  For an input of size n, the outer loop does n iterations and the inner loop does log(n) iterations.  Each line of code in the algorithm does O(1) operations.  What is the time complexity of the algorithm?

32n=Ω(4n){“version”:”1.1″,”math”:”\(3^{2n}=\Omega(4^n)\)”}

Define the function f: {0, 1}3→{0, 1}3. The output of f is obtained by taking the input string and replacing the first bit by 1, regardless of whether the first bit is a 0 or 1. For example, f(001) = 101 and f(110) = 110.  Under this function, what is the preimage of 111?
