One day Faisal was learning about Acceleration. He was reading...
Acceleration may be two types. Such as- uniform acceleration and non-uniform acceleration.
If the rate of increase of velocity of a moving body in a particular direction is maintained constant all the time, then the acceleration is said to be uniform.
Conversely, if the rate of increase of velocity changes with time, the acceleration is said to be non-uniform or variable.
The Velocity of a car decreases uniformly from X ms-1 and after T s it becomes Y ms-1. Now he wanted to find the Acceleration of the car.
The input file contains 3 integers X, Y (-100 <=X, Y <=100) and T (0 <= T <= 200).
For each line of input print the value of Acceleration in a separated line.
