- The outer loop still executes
times in the new version of the algorithm. When the outer loop's counter is i, the inner loop executes
times. If you add up the number of times that the inner loop executes, the result is 
This is still 
although the performance in practice will probably be faster than the original version. - See Table B.1. The value
Infinitymeans that the program can execute the algorithm for any practical problem size. The example programs Ch01Ex02 and ch01_ex02, which are available for download on the book's website, generate these values.Table B.1: Maximum Problem Sizes That Run in Various Times TIME LOG2(N) SQRT(N) N N2 2N N!
