Read a $3-$character string from input into variable userString. Declare a Boolean variable hasDigit and assign hasDigit with true if userString contains a digit. Otherwise, assign hasDigit with false.

Ex: If the input is $66$v$,$ then hasDigit is assigned with true, so the output is:

String is valid

Ex: If the input is byn$,$ then hasDigit is assigned with false, so the output is:

String is not valid

Note: Use userString $=$ scnr$.$nextLine$()$ to read the entire line from input into userString.
