Most of us know about design patterns. But let me give the crux of — what a design pattern is? before getting into the topic.
Design Patterns are the set of solution to typical and most commonly occurring problems in designing software program. They are mostly related to object orient…

Problem statement

Given two queues with their standard operations (enqueue, dequeue, isempty, size), implement a stack with its standard operations (pop, push, isempty, size).


There can be two ways you can solve the above problem.

  • Option A: The stack — efficient when pushing an item
  • Option B: The stack — efficient when…

How insertion sort works?

Insertion sort is a simple sorting algorithm that builds the final sorted array (or list) one item at a time. It works best on a nearly sorted list. It has the following characteristics

  • Stable; i.e., does not change the relative order of elements with equal keys
  • In-place; i.e., only requires…

Data Structure is a particular way of storing and organizing data in a computer so that it can be used efficiently. They can be broadly classified as primitive, composite/abstract/non-primitive data structures. Primitive structures are the basic units of storage like boolean, integer, float, double. These are not that significant when…

MIPS R2000 is a RISC processor. Its ISA has fixed-width 32 bit instructions and fall into one of the following three categories: R-type, I-type, and J-type

MPIS R2000 Instruction set

All the Instructions — can also be grouped under following functional groups.

Arithmetic Instructions: +, -, *, / operations on std data-structures (short, int…

Clock synchronization in computers

Most of the system programmer used the Timer Interrupt for various reasons especially in synchronization. Some of the including me didn’t spent much time on how exactly it works. This post is my attempt to explain my understanding on how it works?

Most of the IBM compatible PCs come with…
