Description: Subjects were asked to achieve order and non-recursive form of the exchange of quick sort algorithm, and random data were compared by sorting algorithms compare the number of keywords and keyword mobile number. (1) to be sorted table table long is not less than 100 which data to use pseudo-random number generation procedures be at least 5 different sets of input data for comparison comparable indicators with the participation of more number of keywords and mobile number of keywords (keyword exchange of dollars for the 3 mobile). (2) the last to make a simple analysis of the results, including the outcome of each set of data to explain the size of fluctuations. (3) of the quick sort algorithm is optimized properly, and sets out the efficiency of comparison before and after optimization.
