Cuban Prime Checker
+
+## Description :-
+
+Cuban Prime Checker is a web application that allows users to identify and find Cuban prime numbers within a specified range.
+
+* Checks if a number is a Cuban prime.
+* Finds Cuban prime numbers within a specified range.
+
+## What is a Cuban Prime?
+
+A Cuban prime is a prime number that is a solution to the Diophantine equation x^3 + y^3 = z^3 + 1, where x, y, and z are positive integers. In other words, it's a special type of prime number related to the sum of cubes.
+
+For example, 2, 19, 37 are Cuban primes as they satisfy the mentioned Diophantine equation.

What is a Cuban Prime?
+
+ A Cuban prime is a prime number that is a solution to the Diophantine equation x^3 + y^3 = z^3 + 1, where x, y, and z are positive integers.
+ It's a special type of prime number related to the sum of cubes.
+
+
+
Formula:
+
+ The Diophantine equation for Cuban primes is x^3 + y^3 = z^3 + 1.
+
+
+
Solution Process:
+
+ When checking a number for Cuban primality, the application verifies if the given number satisfies the Diophantine equation.
+ The application then checks if both the calculated value and the given number are prime. If the conditions are met, the number is identified as a Cuban Prime.
