Explode function is used to split a string into an array of strings based on a delimiter.
The explode function takes in a delimiter and a string as input
It splits the string into an array of strings based on the delimiter
For example, explode(',', 'apple,banana,orange') would return ['apple', 'banana', 'orange']
Find duplicates in a list of elements.
Iterate through the list and keep track of elements seen so far
If an element is already in the seen elements, it is a duplicate
Use a hash set to efficiently check for duplicates
Check if any two strings in the list are anagrams of each other
Iterate through the list and for each string, sort the characters and check if it already exists in a hashmap
If it exists, then the current string is an anagram of the existing string
Return true if anagrams are found, false otherwise

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.
Start from the first element and compare it with the next element
If the next element is smaller, swap them
Repeat this process for all elements in the array
Continue this process until no more swaps are needed

Take input from user for range of numbers
Loop through the range and check if each number is prime
Print the prime numbers
Hashmap is a data structure that stores key-value pairs and allows constant time access to values based on their keys.
Hashmap uses a hash function to map keys to indices in an array.
Collisions can occur when multiple keys map to the same index, which can be resolved using techniques like chaining or open addressing.
Examples of hashmap implementations include Java's HashMap class and Python's dict type.
Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.
Inheritance allows code reuse and promotes code organization.
The existing class is called the parent or superclass, and the new class is called the child or subclass.
The child class inherits all the properties and methods of the parent class and can also add new properties and methods.
