So far, we’ve been enriching our sorting algorithm series with algorithms that are able to sort any type of objects. But what if we needed to sort only integers, and in particular small ints, are these algorithms still the best choice out there? Or do we have more performant ones we can rely on? Well, one of these specialized algorithms goes by Counting Sort and is covered and implemented in this video.

can u explain how this sort works for strings??

@geekific 2 жыл бұрын

Well, counting sort is typically used on integers as we are collecting the frequency of each integer in the array. But, if you would like to do a modified version that instead counts the occurrence of strings, you'd have to first map each string to an index (hashing) and then apply it as shown in the video. However, note that this would not be optimal at all if your array does not contain a lot of frequently repeated strings. Let me know if this answers your question!
