# Use AI to refactor code
# The following code has very verbose variable names and redundant typecasting.
# It also uses a while loop instead of a for loop, which can be less efficient
# and create potential for infinite loops if not handled carefully.
# Your task is to use an AI chatbot to refactor this code to be more concise
# and efficient while maintaining the same functionality.

# Highlight over the code blocks below, then open the AI chatbot interface
# (Ctrl + I) and instruct the chatbot to refactor the code to avoid typecasting,
# poor variable names, and the use of while loops.
