Time limit: 3.000 seconds
A partical 【[电] 质点;】has inital velocity and accerleration【初速度与加速度 】 .If its velocity after certain time is v then what will its displacement be in twice of that time ?
Input
The input will contains 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 partical gainsthat 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
Code: accepted
#include<iostream>
using namespace std;
int main()
{
int v,t;
while(scanf("%d%d",&v,&t)!=EOF)
{
cout<<v*2*t<<endl;
}
return 0;
}
