Merge Sort
Everybody has their favorite algorithms, and merge sort happens to be one of mine. It's also one of the definitive "Divide and Conquer" algorithms. There is a certain elegance to merge sort, and unlike Quicksort, it is a stab
Binary Search Trees
Binary Search Trees are pervasive in computer science, their usefulness can not be overemphasized. From parsing, to searching, to sorting they pop up everywhere, even underpinning other ADT. They offer quick look up times
Rounding Numbers
Rounding numbers is rudimentary math, often times we do it in our head without even realizing we've done it.
