Not understanding Question
Hey @prateekmalhotra051199
According to the Problem the work is to find the Max CB numbers from the given number.
- As to work on substrings of the given number, we will capture the element into the String instead of integer .
- The number ‘n’ given is nothing to do with our approach(as we are working on String) but can be useful acoording to your approach.
Intuition :
- 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.
