Sorting
Also known as: sort algorithm
Rearranging items in a collection into a defined order, such as smallest to largest or alphabetical. Sorted data enables much faster searching and makes output far easier for humans to read.
💡 Intuition
Putting things in order—alphabetical, numerical, by date—so they are easier to find and use.
Core Idea
Different sorting algorithms have different efficiency trade-offs and work better in different situations.
🔬 Example
🎯 Why It Matters
Sorted data enables much faster searching and makes output far easier for humans to read.
⚠️ Common Confusion
Stable sort preserves original order of equal elements; unstable doesn't.
