Hi Raushan, there are 2 mistakes in your code. First that numbers you find and declare as CB numbers are overlapping sometimes. For ex in 5117, valid CB numbers are 5, 11, 7 but your program will count them as 5, 11, 17, 7. You need to fix this by maintaining a record in memory which tells wether a digit at a particular position has been used or not.
Secondly your condition to check wether the the number generated is a CB number or not should be judged in following steps:

  1. check if it is 1 or 0 if yes then its NOT a CB number.
  2. check if it is equal to any of {2, 3, 5, 7, 11, 13, 17, 19, 23, 29}. if yes it’s a CB no.
  3. if it is divisible by any of above nos. its is not a CB no. then

Pls correct these mistakes in your code.
