Read a $3-$character string from input into variable inputString. Declare a Boolean variable noSpaces and assign nospaces with true if inputString does not contain any spaces. Otherwise, assign nospaces with false.

Ex: If the input is $rtv,$ then nospaces is assigned with true, so the output is:

String is valid

Ex: If the input is $6,$ then nospaces is assigned with false, so the output is:

String is not valid

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