Read a $3-$character string from input into variable inString. Declare a Boolean variable isValid and assign isValid with true if

inString does not contain any digits. Otherwise, assign isValid with false.

Ex: If the input is $$ny,$ then isValid is assigned with true, so the output is:

Ex: If the input is $g3c,$ then isValid is assigned with false, so the output is:

Invalid string

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