Question: Write a step-by-step solution for creating a function that converts a given character into its lowercase equivalent. Answer: Step 1: Define the function Create a function called "lowercase" which takes a single character as an input argument. Step 2: Check for uppercase character In the function, check if the input character is an uppercase letter (i.e., it is between 'A' and 'Z'). You can use the character's ASCII values to do this comparison. Step 3: Convert character to lowercase If the input character is an uppercase letter, calculate the difference between its ASCII value and the ASCII value of 'A'. Add this difference to the ASCII value of 'a' to get the ASCII value of the lowercase equivalent. Convert the resulting ASCII value back into a character. Step 4: Return lowercase character or unchanged character If the input character was an uppercase letter, return the lowercase equivalent. If the input character was not an uppercase letter, return the character as it is (unchanged). Step 5: Test the function Test the created function with a few different inputs, including uppercase letters, lowercase letters, and non-letter characters. Verify that the function correctly converts input characters to their lowercase equivalent or leaves them unchanged when appropriate.
