3 test Case Failed getting Wrong Ans

#1

code:

#2

your logic for solving this question is wrong, you are essentially starting from given index and findiing a CB number and then starting from that index, but instead you should look for smaller CB numbers first, for example in case of
4
4567

your code would give 1, i.e 4567 itself, but the correct solution would be 2 i.e 5, 7.
In correct approach we would look for smallest CB number first.

#3

Correct approach:

  • Put loop on string that will give substring of every length.
  • create a function that will return true if the passed number is a CB number otherwise return false.
  • To put a check if the digit is already a part of the any other CB number, create an boolean array say, valid which store which digits till now has been a part of any other CB number.
  • Take a counter and increment if a CB number is found.
  • At the end print the count.
