negative integer indicates the end of the input and is not stored in the array. Convert the last negative integer to positive and use as N$.$ Output the last integer $($as negative$)$ if the size of the array is smaller than N$.$ Assume the array will always contain fewer than $20$ integers.

Ex: If the input is:

$15975-3$

the output is:

$9$

Ex: If the input is:

$12345-6$

the output is:

$-6$
