The program capitalizes the first letter of each reversed word in a sentence.
Split the sentence into an array of words using space as a delimiter.
Reverse each word in the array and capitalize the first letter.
Join the modified words back into a sentence.
Probability of a horse going out of a chessboard in 'n' steps.
The total number of possible moves for a horse is 8.
The probability of going out of the board depends on the position of the horse.
For example, if the horse is at a corner, the probability of going out of the board is higher.
The probability can be calculated using combinatorics and geometry.

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.

Using subqueries in SQL allows for more complex queries by nesting queries within other queries.
Subquery in SELECT statement: SELECT column_name FROM table_name WHERE column_name = (SELECT column_name FROM table_name)
Subquery in WHERE clause: SELECT column_name FROM table_name WHERE column_name IN (SELECT column_name FROM table_name)
Subquery in FROM clause: SELECT column_name FROM (SELECT column_name FROM table_name) A
