What is Bubble Sort?

Bubble Sort is one of the simplest sorting algorithms that works by repeatedly swapping adjacent elements if they are in the wrong order. The algorithm gets its name because smaller elements “bubble” up to the top of the list while larger elements sink down.

How Bubble Sort Works?

1️⃣ Compare adjacent elements in the list.
2️⃣ Swap them if they are in the wrong order.
3️⃣ Repeat this process for the entire list.
4️⃣ With each pass, the largest element moves to its correct position.
5️⃣ Continue this process until the entire list is sorted.

Unsorted List → [64, 34, 25, 12, 22, 11, 90]
✅ Pass 1: [34, 25, 12, 22, 11, 64, 90]
✅ Pass 2: [25, 12, 22, 11, 34, 64, 90]
✅ Pass 3: [12, 22, 11, 25, 34, 64, 90]
✅ Pass 4: [12, 11, 22, 25, 34, 64, 90]
✅ Pass 5: [11, 12, 22, 25, 34, 64, 90]

Time Complexity of Bubble Sort

💡 Best Case (Already Sorted List) → O(n)
💡 Average Case → O(n²)
💡 Worst Case (Reversed List) → O(n²)

Since Bubble Sort compares elements multiple times, it is not the most efficient sorting algorithm for large datasets. However, it is a great way to understand the basic concepts of sorting.
