Challenge Overview

In order to display the output of the `convert_to_snake_case()` function, you need to call the `main()` function.

In order to display the output of the convert_to_snake_case() function, you need to call the main() function.

At the same level as the two existing functions, add a call to the main() function. You should see the given camel or pascal cased string converted to snake case upon execution.

def convert_to_snake_case(pascal_or_camel_cased_string):
    snake_cased_char_list = []
    for char in pascal_or_camel_cased_string:
        if char.isupper():
            converted_character = '_' + char.lower()
            snake_cased_char_list.append(converted_character)
        else:
            snake_cased_char_list.append(char)
    snake_cased_string = ''.join(snake_cased_char_list)
    clean_snake_cased_string = snake_cased_string.strip('_')

    return clean_snake_cased_string

def main():
    print(convert_to_snake_case('aLongAndComplexString'))

main()
