In SQL, the functions used to extract individual components are LEFT, RIGHT, SUBSTRING, and LEN.
what is the LEFT() function?
The LEFT() function retrieves a string's first few characters (starting from the left).
what is the SUBSTRING() function?
A string of characters can be extracted using the SUBSTRING() function.
Once you've identified the characters that divide the parts of a string you want to parse. So the functions that are used to extract individual components are LEFT, RIGHT, SUBSTRING, and LEN.
Therefore, LEFT, RIGHT, SUBSTRING, and LEN functions are used.

What does Quicksort's partition function do?
Partition guarantees that all things less than the pivot come before it and then give the pivot's position back. All the elements in the lower half are known to be less than the pivot, and all the items in the upper half are known to be greater than it, so this satisfies our need for partitioning the problem.
