Implement a function called log that takes one parameter, filename, the name of a file. You may assume the file is in the current working directory of the program. log should prompt the user for their name arid the nature of their visit. log should then append a line to the file named filename in the following format: 1 KNAME OF INDIVIDUAL> Additional requirements e If the user enters empty input, or input that is only whitespace, re-prompt them for valid input before continuing.
