Consider searching algorithms on the following array of data:
[22 21 9 4 16 2 10 14 20 31 26 19 17 28 8 13]
Suppose you want to implement a searching algorithm to see if the data set contains the number 19. Demonstrate how the search would go if you used:
A sequential search
A binary search
Suppose an algorithm that processes a data set of size 8 has a runtime of 72. The same algorithm has a runtime of 110 when applied to a data set of size 10; and when applied to a data set of size 20, it has a runtime of 420. Using big-O notation, state the runtime for this algorithm for the general case of a data set of size n.
Suppose you develop an algorithm that processes the first element of an array (length of n), then processes the first 2 elements, then the first 3 elements, and so on, until the last iteration of a loop, when it processes all elements. Thus, if n = 4, the runtime would be 1 + 2 + 3 + 4 = 10.
Create a table that depicts the runtime for arrays of length 1 to 10. Would you expect the general runtime to be O(n), O(n2), O(n3), or some other function of n? Explain.
