Bubble sort compares adjacent elements and performs swaps to push larger elements toward the end. In the worst case (reverse sorted list), the number of comparisons is:

**Why Bubble Sort Still Matters: Sorting the Digital Landscape with Clarity and Precision** In a world shaped by data, the way we organize information matters more than ever. One fundamental algorithm that continues to attract attention is bubble sort — a method where adjacent elements are repeatedly compared and swapped to position larger values toward the end. Especially in edge cases like reverse-sorted inputs, this approach delivers a predictable pattern of comparisons that reveals true computational complexity. But why does this simple sorting algorithm remain relevant, especially in technical discussions shaping software design and performance optimization? **Why Bubble Sort Compares Adjacent Elements and Pushes Larger Ones Forward – Naturally in the Worst Case** At its core, bubble sort relies on the continuous scanning of a list from front to back. Each pass moves the largest unplaced element to its correct position at the end of the sequence. This process depends entirely on checking pairs of adjacent items — comparing their values to decide whether a swap is needed. The more out-of-order a list is, the more full and repeated these comparisons become. In the worst-case scenario — a reverse-sorted list — every element triggers a full cycle of checks, maximizing the number of comparisons. This structure makes bubble sort a clear case study for analyzing algorithmic efficiency.
