ACID properties in DBMS ensure data integrity and consistency in transactions.
Atomicity: All operations in a transaction are completed successfully or none at all.
Consistency: Data is always in a valid state before and after a transaction.
Isolation: Transactions are executed independently without interference from other transactions.
Durability: Once a transaction is committed, changes are permanent and cannot be lost.

Object-oriented programming concepts that focus on classes and objects
Encapsulation: Bundling data and methods that operate on the data into a single unit (class)
Inheritance: Ability of a class to inherit properties and behavior from another class
Polymorphism: Ability to present the same interface for different data types
Abstraction: Hiding the complex implementation details and showing only the necessary features

Return max_so_far
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.
