What is a code to longest Common Prefix using Character by Character Matching and the other steps required given the following:
Longest Common Prefix using Character by Character Matching | A Function to find the string having the minimum length and returns that length.
A Function that returns the longest common prefix from the array of strings.
Our resultant string char current.
The current character.
Current character ( must be same in all strings to be a part of result ).
Append to result.
Driver program to test above function"
How can the above be solved in Python?
