Example: Incorrect time complexity (page 55)

Notice the inefficiency here. As the number of elements increases, the number of steps grows exponentially. We can see this clearly in the following table:
N Data Elements Max # of Steps
5 20
10 90
20 380
40 1560
80 6320

This is polynomial (quadratic) growth, not exponential!
