Hashmap is a data structure that stores key-value pairs and uses hashing to quickly retrieve values.
Hashmap uses an array to store the key-value pairs
The key is hashed to get an index in the array
If there is a collision, chaining or open addressing is used to resolve it
Hashmap has O(1) time complexity for insertion, deletion and retrieval
Java's HashMap uses chaining to resolve collisions
Hashmap is a key-value pair data structure while ArrayList is a dynamic array.
Hashmap allows null values and keys while ArrayList doesn't allow null values.
Hashmap provides constant time complexity for basic operations while ArrayList has linear time complexity.
Hashmap is unordered while ArrayList is ordered.
Hashmap is ideal for storing and retrieving data based on keys while ArrayList is ideal for maintaining a collec

Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order.
Compares adjacent elements and swaps them if they are in the wrong order
Repeats this process until the list is sorted
Not efficient for large datasets, has a time complexity of O(n^2)
A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward as forward.
Palindrome is a word, phrase, number, or sequence that reads the same forwards and backwards.
Examples: 'radar', 'madam', '1221', 'A man, a plan, a canal, Panama.'
Merge sort is a divide and conquer algorithm that recursively divides the array into two halves, sorts them, and then merges them back together.
Divide the array into two halves
Recursively sort each half
Merge the sorted halves back together
