Read a $2-$character string from input into variable userString. Declare a Boolean variable isValid and assign isValid with true if userString does not contain any lowercase letters. Otherwise, assign isValid with false.

Ex: If the input is $S8,$ then isValid is assigned with true, so the output is:

String accepted

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

String not accepted

Note: Use getline $($cin$,$ userString$)$ to read the entire line from input into userString.
