Description:

A particle has initial constant velocity. For a particle with initial velocity v find the displacement of that

particle if the time t is doubled.


Input:

The input will contain two integers in each line. Each line makes one set of input. These two integers

denote the value of v (-10000 <= v <= 10000) and t(0<=t<= 500) ( t means at the time the particle gains

that velocity)


Output:

For each line of input print a single integer in one line denoting the displacement in double of that time.

Sample Input:

0 0
5 12

Sample Output:

0
120

Note:

undefined
