Endianness refers to the byte order of a system. It determines how multi-byte data types are stored in memory.
Little-endian systems store the least significant byte first, while big-endian systems store the most significant byte first.
Endianness can affect the way data is transmitted between systems.
To determine the endianness of a system, you can use the byte order mark (BOM) or write a test program that checks the by...
Sort an array of 0's and 1's only.
Use two pointers, one at the beginning and one at the end of the array.
Swap 0's from the beginning with 1's from the end until the pointers meet.
Alternatively, use a counting sort algorithm to count the number of 0's and 1's and then reconstruct the array.
Heaps are data structures used to efficiently find the maximum or minimum element in a collection.
Max heap: parent nodes are always greater than or equal to child nodes
Min heap: parent nodes are always smaller than or equal to child nodes
Heaps are commonly used in priority queues and sorting algorithms
Heap operations include insert, delete, and extract max/min
Example: An array [3, 8, 2, 5, 1, 4, 6] can be represented a
Find 3 numbers in an array where a+b=c.
Loop through the array and check for all possible combinations of a and b.
Use a hash table to store the values of a and b, and check if c is present in the hash table.
Sort the array and use two pointers to find a and b, and then check if their sum equals c.

Types of encryption include symmetric encryption, asymmetric encryption, and hashing.
Symmetric encryption: Uses the same key for both encryption and decryption, examples include AES and DES.
Asymmetric encryption: Uses a pair of public and private keys for encryption and decryption, examples include RSA and ECC.
Hashing: Converts data into a fixed-size string of bytes, examples include MD5 and SHA.
Polymorphism is a key feature of OOP in C#. Extension methods allow adding new functionality to existing types.
Polymorphism allows objects of different classes to be treated as if they are of the same type.
Extension methods are static methods that can be called as if they were instance methods of the extended type.
Polymorphism and extension methods can be used together to add new behavior to existing types without modi
