Topics The Test Program Evaluation Results

Evaluation of List Implementations The functions of the various List classes were tested by executing each of them 1,000,000 times and computing the average execution time. Run times are expressed in microseconds. All functions were applied to a list of 1000 elements.

Evaluation of List Implementations The function GetElement() accessed positions both sequentially and randomly in the list. The functions Insert() and Delete() accessed elements randomly in the list.
