** Back to High School Physics ** ** Input: ** standard input ** Output: ** standard output A particle has initial velocity and constant acceleration. If its velocity after certain time is v then what will its displacement be in twice of that time? ** 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 (-100 <= v <= 100) and t(0<=t<= 200) ( 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
 * Problem B **

** Sample Output ** 0
