When learning sorting algorithms, two of the most common examples are bubble sort and selection sort. I built a Python program in Trinket.io using Pygame to visualize selection sort, and I compare it with bubble sort side by side in my video. 💡 Which one do you think will finish first?
What is Selection Sort?
Selection sort works by repeatedly finding the smallest element in the unsorted portion of the list and swapping it with the element in the current position. Over time, the list becomes sorted from front to back.
This is different from bubble sort, which relies on swapping adjacent elements so that larger values “bubble up” toward the end of the list.
Why It’s Useful
- Easy to understand
- Great for learning sorting logic
- Not efficient for large datasets (time complexity O(n²))
