C program to find the total number of digits in a number.
Question: The problem of counting the digits in a positive integer or summing those digits can be solved recursively. For example, to count the number of digits think as follows: If the integer is.
There is a pattern in binary representation of the number that can be used to find if number is a multiple of 3. If difference between count of odd set bits (Bits set at odd positions) and even set bits is multiple of 3 then is the number. Example: 23 (00.10111) 1) Get count of all set bits at odd positions (For 23 it’s 3).

C Programming-Write an Efficient Method Check if a Number is Multiple of 3 -If sum of digits in a number is multiple of 3 then number is multiple of 3 e.g.
This is the second part of our article to solve this coding interview question, how to find the sum of digits of an integer number in Java. In the first part, we have solved this problem without using recursion i.e. by using a while loop and in this part, we will solve it by using recursion.It's good to know different approaches to solving the same problem, this will help you to do well on.
That means the logarithm of a number is the exponent to which another fixed value, the base, must be raised to produce that number. In simple cases the logarithm counts repeated multiplication.
