What is a code to generate a string which differs by only a single character from all given strings and the other steps required given the following:
Generate a string which differs by only a single character from all given strings | Function to check if a given string differs by a single character from all the strings in an array.
Traverse over the strings.
Stores the count of characters differing from the strings.
If differs by more than one character.
Function to find the string which only differ at one position from the all given strings of the array.
Size of the array.
Length of a string.
Replace i - th character by all possible characters.
Check if it differs by a single character from all other strings.
If desired string is obtained.
Print the answer.
Driver Code.
Function call"
How can the above be solved in Python?
