String password is read from input. For each character in password that is a letter, increment count by $1.$ Then, output "Valid" if count contains fewer than $6$ letters and password's length is greater than $7.$ Otherwise, output "Invalid". End each output with a newline.

Ex $1$: If the input is n$62$d$5$RMs$,$ then the output is:

Ex $2$: If the input is Qyhpscl$,$ then the output is:

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.
