Finding cb num - doubt
Hi @Aayush_25, pls re-read the question and attempt it again. It has nothing to do with prime numbers. There are 2 parts of this question, solve both of them with a straightforward approach, nothing complex is needed here.
Hope this helps 
correct me if i’m wrong but the question indirectly defines CB numbers as prime numbers only…
secondly i assume the 2 parts you are referring to are checking for cb number and generating substrings and i considered both of them
Hi @Aayush_25 , that’s not true. Because you can see that the numbers listed over there are not all of the prime numbers, right ! And your code considers all the prime numbers as CB numbers. And yeah, the 2 parts i am referring to are that only.
OK if this helps, how about approaching / making algo for this question directly. Like, as mentioned in the question. Do directly what the question is asking.
Hope this helps
