Declare a Boolean variable named isValid. Use isValid to output "Valid" if secretStr contains more than $2$ digits and secretStr$\text{'}$s length is less than $8.$ Otherwise, output "Invalid".$$Ex: If the input is l$0$dW$75$N$,$ then the output is:$$Valid$$Ex: If the input is k$90$lzKsC$,$ then the output is:$$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.
