Quicksort[edit]

I have reverted your edit in Quicksort because it was wrong. --CiaPan (talk) 07:36, 15 September 2015 (UTC)[reply]

PS.

The (pseudo)code you put was simply syntactically incorrect. See the section: there is a while True loop there, which contained one do ... while loop to decrement j, another do ... while loop to increment i.
Your do j = j - 1 looks somewhat like an incomplete loop, but it's hard to tell why it decrements j and it is completely unknown how long it should iterate.

However despite its incompleteness, the instruction to decrement j at that point simply makes the code wrong. The first do ... while loop sets appropriate value of j and decrementing it any further would bring a wrong value to a comparision in the following if i < j condition. --CiaPan (talk) 07:54, 15 September 2015 (UTC)[reply]

Oh, I get it. I was looking at it like a while loop instead of a do..while loop. I thought that only the i was being incremented, and j was not, which wouldn't have made any sense. Thanks for clearing that out for me. Iamseiko (talk) 01:40, 16 September 2015 (UTC)[reply]
