Declare a Boolean variable named allEqual. Then, read integer numInput from input representing the number of integers to be read next. Use a loop to read the remaining integers from input. If all numInput integers are equal to $-1,$ assign allEqual with true. Otherwise, assign allEqual with false.

Code at the end of main$()$ outputs "All equal $-1"$ if allEqual is true or "Some values are not $-1"$ if allEqual is false.

Ex: If the input is:

$3$

$-1-1-1$

then the output is:

All equal $-1$c$++$
