Reduce the digits:
You are given a positive integer N, write a program to repeatedly add the digits of the number until the number becomes a single-digit number.
Input:
The input should be a single line containing a single-digit number.
Output:
The output should be a single line containing a single-digit number.
Explanation:
In the example, the given number is 92. As the number is more than a single digit, repeatedly add the digits like
9+2=11
1+1=2

Problem Statement:
In First and Last Digits in Python, we are given two positive numbers, we need to find the count of those numbers which have the same first and last digit. Also, if the number is below 10 it will also be counted. For example, 1, 2, 3, 4, … ,9. will be counted.
Code for First and Last Digits in Python:
n1 = 5
n2 = 203
count = 0
for i in range[n1, n2 + 1]:
if i
