Implement the fix$\_$capitalization$()$ function. fix$\_$capitalization$()$ has a string parameter and returns an updated string, where lowercase letters at the beginning of sentences are replaced with uppercase letters. fix$\_$capitalization$()$ also returns the number of letters that have been capitalized. Call fix$\_$capitalization$()$ in the execute$\_$menu$()$ function, and then output the number of letters capitalized followed by the edited string. Hint $1$: Look up and use Python functions $.$islower$()$ and $.$upper$()$ to complete this task. Hint $2$: Create an empty string and use string concatenation to make edits to the string. $(3$ pts$)$
