Foreach
The "foreach" loop is a special case of the for loop, usually enacted on a linear container such as an array or a list, where for every iteration of the loop, some action is performed on a member of the container until that actio
Computer Sciences better mouse trap
In the beginning the large majority of sort implementations were the more commonly known quadratic sorts: selection sort, insertion sort, and the omnipresent bubble sort. Radix sort was in use for the physic
Quicksort
In my previous post on quick sort I covered in detail the recursive implementation of the famous sorting algorithm. In that post I mentioned that a downside of quick sort is that it has the potential to encounter worst-case quadrati
If you were stuck on a desert island with just one data structure, which would it be and why?
This is a silly but fun question, and after giving it some thought, my answer most likely shouldn't surprise most readers: A balanced binary se
Bloom Filters
Bloom filters have been around for a while, 1970 to be exact. They're not exactly the star of any university data structures class. There are much "sexier" (yeah, i know.) data structures like self balancing search trees, hash t
