C++: Read integers from input and store each integer into a vector until -1 is read. Do not store-1 into the vector. Then, output all values in the vector (except the last value) with the last value in the vector added to each value. Output each value on a new line.
Ex: If the input is -24 28-48-1, the output is:
-16
36
4
(I've been trying to use push_back and pop_back but I'm clearly messing up somewhere and I don't know where)
