Question 1
The time complexity for the insertion sort algorithm in the text is ________.
◦ O(2^n)
◦ O(logn)
◦ O(nlogn)
◦ O(n^2)
Question 2
________ approach is the process of solving subproblems, then combining the solutions of the subproblems to obtain an overall solution. This naturally leads to a recursive solution. However, it would be inefficient to use recursion, because the subproblems overlap. The key idea behind dynamic programming is to solve each subproblem only once and store the results for subproblems for later use to avoid redundant computing of the subproblems.
◦ Dynamic programming
◦ Backtracking
◦ Divide-and-conquer
◦ Brutal-force
