Integers are read from input and stored into a vector until $-1$ is read. For each vector element E$,$ output the result of subtracting the vector's last element from E$.$ End each number with a newline.

Ex: If the input is $0-3-97-1,$ the vector's last element is $7.$ Thus, the output is:

$-7$

$-10$

$-16$

$0$
