Declare a Boolean variable named goodPasswd. Use goodPasswd to output "Valid" if passPhrase contains more than $3$ letters and passPhrase's length is greater than or equal to $6.$ Otherwise, output "Invalid".

Ex: If the input is M$3$pz$9$D$,$ then the output is:

Valid

Ex: If the input is ZQR$1$f$,$ then the output is:

Invalid

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