Py Sorting Searching in Python
Sorting and searching are the most fundamental algorithms in computer science. Every ranked list, search engine result, and database query uses them under the hood.
Bubble Sort: The simplest sorting algorithm. Compare adjacent elements, swap if in wrong order. Repeat until no swaps needed. Time: O(n²) — slow for large data but easy to understand and implement. Good for learning; rarely used in production.
Binary Search: The fastest way to search a SORTED list. Instead of checking every element (O(n)), binary search checks the middle, eliminates half the remaining elements, and repeats — achieving O(log n) speed. For 1 million items: linear = 1,000,000 checks; binary = 20 checks!
Python built-ins: sorted() and list.sort() use Timsort (O(n log n)) — much faster than Bubble Sort. In operator (in) does linear search. bisect module does binary search. For competitive programming and CBSE: understand Bubble Sort, Linear Search, Binary Search.
Py Sorting Searching — Syntax
# Bubble Sort: O(n²) # Compare neighbors, swap if needed, repeat # Linear Search: O(n) # Check each element one by one # Binary Search: O(log n) # Only works on sorted data # Check middle → go left or right → repeat
