Course design of data structure -- exchange sequencing assignment

Title Requirements:
Comparison of exchange sort
[basic requirements]
(1) Generate a set of random numbers to store in order and output.
(2) One way bubble sorting and two-way bubble sorting are used for sorting, and the comparison times and movement times of each algorithm are counted at the same time, and the results are displayed.
(3) The fast sorting method is used for sorting, and the number of comparison and movement are counted at the same time to display the results.
(4) Determine whether a set of data is in order.
(5) Set all odd numbers before even.
(6) Choose to do: find a set of data in the k-th position by value size (no need to sort).
