Read a $3-$character string from input into variable inputString. Declare a Boolean variable isValid and assign isvalid with true if the first and third characters of inputString are both alphabetic characters. Otherwise, assign isValid with false.

Ex: If the input is $r-k,$ then is Valid is assigned with true, so the output is:

String accepted

Ex: If the input is $s98,$ then is Valid is assigned with false, so the output is:

String not accepted

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