+
+## Description :-
+
+This is a simple web application that allows users to check if a given number is a fascinating number or not. 
+A fascinating number is a positive number which contains all the digits from 1 to 9 exactly once and does not contain any 0's
+after Concatenating number(x) with the numbers 2 * x and 3 * x. 
+
+For example, the number 192 is fascinating because (192 * 2 = 384 and 192 * 3 = 576) and after concatenating it become (192384576) which contain all the digits from 1 to 9.
