Whilst learning algorithms I came across this video and wanted to share and tip my hat to YK at CS Dojo

Many of the videos on algorithms I come across seem dive in to the deep end, and at least for me can be quite confusing and take some time to grasp.

A day or two later I seem to have already forgotten the underlying concept being taught, as maybe I was bamboozled by the task itself.

This is a really succinct, short and to the point video that really leaves you with a clear understanding of how a data structure combined with a simple algorithm can reduce time complexity and one that will stick in the mind long after.

Many thanks YK!

Have a watch.
