Imperative and Functional Merge Sort in OCaml
So happy to be back! The last two week I was running around seeing doctors, lab technicians, etc because I had a mysterious lump on my neck. It’s still there, but they figured out that…

Merge Sort and the Divide and Conquer Approach
Algorithm Design Techniques In earlier posts, I went through the insertion sort and the selection sort algorithms. They both use the incremental approach. Each step of the algorithms sorts one element, and thus the algorithms…
Functional Style Selection Sort in OCaml
In this post I talk about what I have tried and learnt in the process of writing the functional correspondence of the imperative selection sort I wrote earlier in OCaml. I learnt a lot in…
Imperative Style Selection Sort in OCaml
Exercise 2.2-2 of the book Introduction to Algorithms introduced the selection sort algorithm. I decided to write it in OCaml in imperative style. The selection sort algorithm sorts a list first by switching places of…
The Efficiency of an Algorithm
We need to analyze algorithms to choose the most efficient algorithm to implement. One important aspect we look at is the running time of an algorithm, which often depends on the size of input. (See…
Imperative and Functional Insertion Sort in OCaml
I wrote the insertion algorithm in both imperative and functional styles in OCaml! I talk about the fun and challenges of each style below: Imperative Insertion Sort I strictly follow the pseudocode on p.18 of…
Pseudocode, Insertion Sort and Loop Invariant
Pseudocode In Chapter 2 of Introduction to Algorithms, the authors introduce pseudocode. Pseudocode is a way to describe algorithms. Pseudocode is not computer code and is not typically concerned with issues of software engineering (e.g.,…
Introduction to Algorithms
What is an algorithms? From chapter 1 of Introduction to Algorithms, an algorithm is any well-defined procedure that transforms a set of input to a set of output with desired properties. It is a tool…
Algorithms
To be an awesome software engineer, you should know the common algorithms and data structure well. I’m starting my algorithms learning with this book. It is commonly regarded as the best book for learning algorithms. …
