//Write a prigram to accept a number and check it is a fascinating number or not.
// A fascinating number is one which when multiplied by 2 and 3, and then after the results
//are concatenated with the original number, the new number contains all the digits from 1 to 9
//exactly once. example 192
//192 x 1=192 ; 192 x 2=384 ; 192 x 3=576; now concatenating the result =192384576.
