Define the function CheckValues$(0$ with no parameters that reads integers from input until $1$ is read. The function returns true if none of the integers read before $1$ are between $-2000$ and $-1000$ inclusive. Otherwise, the function returns false.

Ex: If the input is $2-1500-9701,$ then the output is:

Unallowed value $($s$)$

$1$ #include
