Algorithm’s Efficiency | Big O “In Simple English”

Let’s start with a short popular fun story:

I’m originally from the D.R.Cong, in Central Africa and we have a very low internet speed. For illustration, opening a Gmail might take about 3 to 5 min of loading time (sometimes the whole process might just failed and time out).

In 2009, a company in South Africa had a similar issue: “really slow internet speed”. The company had two offices located about 50 miles away from each other and they decided to set up a fun test to see if it would be faster to transfer data over their very much slow internet or via carrier pigeon .

So they stored 4GB of data in a USB drive, strapped it to a pigeon and flew it from one office to the other office, 50 miles away . Guess what…

The carrier pigeon beat the internet .

The pigeon won by a huge margin otherwise it wouldn’t be a fun story. Furthermore, Only about 4% of the data was sent through the internet as the pigeon reached the second office located 50 miles away in 2 hours .

Useful tip:Use Bit ( Github ) to encapsulate components with all their dependencies and setup. Build truly modular applications with better code reuse, simpler maintenance, and less overhead.
