## Problem Description

In Math, I am sure all of your would have known the equation of a straight line in a graph: y = mx + c. Your task is to now to create a program that finds the y-intercept of the line provided the line is in the form y = mx + c.

## Input

The input will consists of 2 integers, *m* followed by *c*, where the equation of the straight line is y = *m*x + *c*.

*m* and *c* can all fit into 32-bit signed integers (int).

## Output

Output, on a singe line, the y-intercept of the line.
