Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if needed.

• Works by repeatedly comparing adjacent elements.

• If the first element is greater than the second, they are swapped.

• This process is repeated until no swaps are needed.

• Example: Sorting [5, 3, 8, 4] results in [3, 4, 5, 8] after several passes.

• Time complexity is O(n^2) in the worst cas...read more

A palindrome is a string that reads the same forwards and backwards, like 'racecar' or 'level'.

• Definition: A palindrome is a word, phrase, or sequence that reads the same backward as forward. Examples include 'madam' and '12321'.

Detect loop in a linked list by using Floyd's cycle detection algorithm.

• Use two pointers, slow and fast, to traverse the linked list.

• If there is a loop, the fast pointer will eventually meet the slow pointer.

• Example: 1->2->3->4->5->2 (loop back to 2), slow and fast pointers will meet at node 2.
