Declare a Boolean variable named isValid. Use isValid to output "Valid" if codeStr contains at least $2$ digits and codeStr's length is less than $10.$ Otherwise, output "Invalid".

Ex: If the input is RH$6$fb$1$LZh$,$ then the output is:

Valid

Ex: If the input is RNxTtJgdm$3,$ then the output is:

Invalid

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