To reverse a string without using any looping and inbuilt functions, we can use recursion.
Create a function that takes a string as input.
If the length of the string is 0 or 1, return the string.
Otherwise, call the function recursively with the substring starting from the second character and concatenate the first character at the end.
Return the reversed string.
Example: reverseString('hello') returns 'olleh'.
A priority queue can be implemented using a single queue or multiple queues.
One approach is to use a single queue and assign priorities to elements using a separate data structure.
Another approach is to use multiple queues, each representing a different priority level.
For example, if there are three priority levels, three queues can be used to implement the priority queue.
An array of objects can be used to implement a heterogeneous array.
Each element in the array can be an object that represents a different data type.
The objects can have different properties and methods based on their respective data types.
For example, an element can be an object representing a string with a 'value' property and a 'length' method.

L - Liskov Substitution Principle: Objects of a superclass should be replaceable...
I have used the Singleton design pattern in my previous projects.
Singleton pattern ensures a class has only one instance and provides a global point of access to it.
It is useful when you want to control the number of instances that can be created.
