Find the middle digit of a given Number

06 May, 2021
Given a number N, the task is to find the middle digit of the given number N. If the number has two middle digits then print the first middle digit.
Examples:  
Input: N = 12345 Output: 3
Input: N = 98562 Output: 5  
Approach: The middle digit of any number N can be given by 
The length(len) of the given Number can be calculated as 
For example:  
If N = 12345 len = (int)log10(12345) + 1 = 5 Therefore, First half of N = N/105/2 = N/102 = 123 Therefore middle digit of N = last digit of First half of N = (First half of N) % 10 = 123 % 10 = 3 
Below code is the implementation of the above approach: 
C++
Java
Python3
C#
Javascript
