Question

Find the number of digits between 1 to N

example:

1. I/P = 10 O/P=11
2. I/P=4 O/P=4
3. I/P = 13 O/P=17
4. I/P=111 O/P=225

and so on...

Answer 1

def findDigits(N):

    if N == 1:
      return 1
# changing number to string 
s = str(N)
# Add length of number to total return len(s) + findDigits(N -
# Driver code 
# Given N
N = 13
# Function call
print (findDigits(N))
Output: 17
