Challenge: Find the Previous Alphabet
Test your understanding of the concepts we have covered so far by solving a simple challenge.
We'll cover the following
Problem statement
In this challenge, you are given a character that is stored in a variable named character
. Your task is to write a code that makes the same variable, character
, now store the character preceding the one originally stored in it. For example, if the variable stored C originally, your code should make it store B.
Input
We have already initialized the variable character
at the backend.
character = 'B'
Output
The value stored in the variable
character_before
should be the previous character.
character_before = 'A'
📝 Please use the variables
character
andcharacter_before
for input and output, respectively, or your code will not execute.
Coding exercise
Before diving directly into the solution, try to solve it yourself. Then, check if your code passes all the test cases. If you get stuck, you can always see the given solution.
Good luck! 👍
