Understanding Sorting Algorithm

I was once asked years ago if I know any sorting algorithm and I terribly failed to answer. As a self taught coder I never encounter having to sort records manually. Because most programming languages have a function already built-in to do this ‘sort’ of thing (pun intended).

So what is it? You my future self should already know the gist of it. Its basically a way to sort set of records based on from lowest or highest to lowest. There are bunch of sorting algorithm listed in this below link:

Different types of sorting algorithms

The most common one is Bubble sorting, you take the first value in the collection or array and compare to the second, if second value is lower, you swap the second to the first. Then we take the second value and compare to the third. Every swap you flip a flag that a swap has happen. You just keep repeating until the swap flag remain false and then everything should be sorted.

For more detailed videos of known sorting algorithm whenever you need it below are full explanations.
