Compare the count you get this way with the count… Re: Testing counting of swaps with insertion, bubble, selection and quick sort 12 Years Ago by bguild I notice that you sort the same array 4 times. This puts bubble sort at a huge disadvantage because it is the only one that has to sort an unsorted list. Once bubble sort is finished, the rest of the sorts will find the array pre-sorted, which should greatly reduce the required swaps. Re: Swaps between all the elements of a vector 13 Years Ago by mrnutty >>[B]for(int high = n-1; i= low; high-- )[/B] Check the condition. The expression syntax is [icode] for(variable decleration,condition, operations)[/icode] When you say "i = low" as a condition, you are saying "i = 0" since low is 0, which is false since 0 is considered false.

Simple Code Piece Really... Re: Counting Quicksort sorting swaps 12 Years Ago by HankReardon Thank you for your keen insight into this matter. I am suprised at how inefficient the quicksort method is compared to the insertion and selection sort. The insertion and selection sort seems to be the number of elements to sort while the quicksort seems to be 10 - times the number of elements needed to be sorted. That is with sorting 10000 numbers… Re: Counting Quicksort sorting swaps 12 Years Ago by JamesCherrill > Should you check for equality before swapping? The detailed argument depends on whether the array is of a primitive type or contains objects. For two primitives an equals test will be trivial, and a swap pretty trivial too. For objects you will use a Comparator to determine the sort order. That returns an int value that tells you whether … Re: Insertion Swaps Counting Number Of 12 Years Ago by HankReardon Wow, this is awesome, it will take me a few to digest but I will look at it, thanks. Re: Insertion Swaps Counting Number Of 12 Years Ago by HankReardon Hello bguild, First, thank you for the good assistance. You are a lifeline to me in this storm on the high seas of data. After looking at your code I think my method is the simplest for doing insertion sorting. Why, because the *while* loop is designed to just move the scan around while the *swap* statement after the *while* loop actually makes a … Re: Insertion Swaps Counting Number Of 12 Years Ago by HankReardon I see the error in my ways.
