Package for this problem was not updated by the problem writer or Codeforces administration after we’ve upgraded the judging servers. To adjust the time limit constraint, solution execution time will be multiplied by 2. For example, if your solution works for 400 ms on judging servers, then value 800 ms will be displayed and used to determine the verdict.

standard inputoutput

standard outputOn a number line there are *n* balls. At time moment 0 for each ball the following data is known: its coordinate *x*_{i}, speed *v*_{i} (possibly, negative) and weight *m*_{i}. The radius of the balls can be ignored.

The balls collide elastically, i.e. if two balls weighing *m*_{1} and *m*_{2} and with speeds *v*_{1} and *v*_{2} collide, their new speeds will be:

Your task is to find out, where each ball will be *t* seconds after.

Input

The first line contains two integers *n* and *t* (1 ≤ *n* ≤ 10, 0 ≤ *t* ≤ 100) — amount of balls and duration of the process. Then follow *n* lines, each containing three integers: *x*_{i}, *v*_{i}, *m*_{i} (1 ≤ |*v*_{i}|, *m*_{i} ≤ 100, |*x*_{i}| ≤ 100) — coordinate, speed and weight of the ball with index *i* at time moment 0.

It is guaranteed that no two balls have the same coordinate initially. Also each collision will be a collision of not more than two balls (that is, three or more balls never collide at the same point in all times from segment [0;*t*]).

Output

Output *n* numbers — coordinates of the balls *t* seconds after. Output the numbers accurate to at least 4 digits after the decimal point.
