Declare a Boolean variable named passwordValid. Use passwordValid to output "Valid" if passwdStr contains no more than $5$

letters and passwdStr's length is less than $10.$ Otherwise, output "Invalid".

Ex: If the input is $05$ fMV$8$Y$9$W$,$ then the output is:

Valid

Ex: If the input is gh$9$zjd$5$GSC$,$ then the output is:

Invalid

Note: isalpha$()$ returns true if a character is a letter, and false otherwise. Ex: isalpha$(\text{'}$a$\text{'})$ returns true. isalpha$(\text{'}8\text{'})$ returns false.
