CodePudding user response:

If the letter to sort, the time complexity of each algorithm are set, this can query,
But you this is to select the minimum 10, not all of them all, I feel are not suitable for, actually exchange method, run 10 times can out results,
Your request is not sorted, minimum 10 to be found,
