Miscellaneous Topics algorithm

Hash Algorithm :

• Hash Algorithm is a Hash function that takes a string of any length and decreases it to a unique fixed length string.
• It is used for password validity, message & data integrity and for many other cryptographic systems.
• A Hash table is (related to a Hash Function) a data structure for storing values to keys of arbitrary type. The Hash table consists of an index into an array by using a Hash function.

Recursive Algorithm :

• Recursive algorithm is a method of solving a complicated problem by breaking a problem down into smaller and smaller sub-problems until we get the problem small enough that it can be solved easily. The result will come out from smallest sub-problems and move top/upward.
• Usually, it involves a function calling itself.
