Bubble Sort and Selection Sort: Two Sorting Techniques

Bubble Sort and Selection Sort are two classic methods for sorting things, like numbers. They might look similar at first, but they work in different ways. Let's break it down!

Bubble Sort:

• This method goes through the list again and again.
• It looks at two items next to each other and checks if they are in the right order.
• If they aren't, it swaps them around.
• It keeps doing this until everything is arranged correctly.
• In most cases, it takes a lot of time to finish, which is noted as $O(n^2)$.

Selection Sort:

• This method splits the list into two parts: sorted and unsorted.
• It finds the smallest (or biggest) item in the unsorted part and moves it to the end of the sorted part.
• It also takes about the same amount of time to finish, marked as $O(n^2)$, but makes fewer swaps than Bubble Sort.

In summary, Bubble Sort is like bubbling items up to their correct spots, while Selection Sort is about picking out the right items one by one!
