[@makingachanneltopost]

I would just like to say I really, really like Abdul Bari's teaching technique. I've been in the Silicon Valley as a developer for almost 20 years, and I wish there were more teachers like Abdul. He has a very graceful style of teaching that I wish more teachers would adapt. I like that he doesn't just jump into material, instead he says "I'm going to teach you X, Y, and Z", and then he repeats "this is how you do X, Y, and Z", then he teaches the material. I don't care how long you've been in the computer science field, there's always something to learn from someone, and Abdul has a lot of good lessons to teach.

[@davidjames1684]

If you want to know if a range of integers has been seen or not already on input, an array of flags would suffice. You could just prescan the array to determine the lowest and highest values (such as 3 is the lowest and 50 is the highest), then you can just make the array from 3 to 50. Space is not really an issue but if you had a low of 3 and a high of say 1 million and not much in between, you could have an "on the fly" hash function that modifies itself to force "oddball" numbers into a smaller space "on the fly" with minimal collisions.

[@andrewtol8756]

Thank you for your clear explanation. :-) One question I had is regarding quadratic probing. You said that it helps to avoid collision element clustering -- and it did, but it seems that it still requires the same number of lookup steps as it would need if linear probing had been applied and clustering had occurred. Ex: Suppose, as in the last example, that the key space is: 8, 3, 13, 23, 43, 10. Then, using linear probing: 3 is stored at index 3, 13 is stored at index 4, 23 is stored at index 5. // That's 3 index checks: h'(x) = [h(x) + f(i)] % 10, for f(i) = i, where i = 0, 1, and 2. Using quadratic probing: 3 is stored at index 3, 13 is stored at index 4, 23 is stored at index 7. // That's 3 index check: h'(x) = [h(x) + f(i)] % 10, for f(i) = i^2, where i = 0, 1, and 2. So, I'm wondering what the benefit is of using quadratic probing to avoid collision clustering? It still requires the same number of basic computations to lookup and element, it seems.
