Declare a Boolean variable named allValid. Then, read integer numVals from input representing the number of integers to be read next. Use a loop to read the remaining integers from input. If all of the numVals integers are in the range $-2000$ to $-1000$ inclusive, assign allValid with true. Otherwise, assign allValid with false.

Code at the end of main$()$ outputs "All valid" if allValid is true or "Has non$-$matching value$($s$)"$ if allValid is false.

Ex: If the input is:

$2$

$-1500-985$

then the output is:

Has non$-$matching value$($s$)$C$++$
