KONO face problems da!
Subject description
GFL has opened a new activity, this time to fly four satellite has finally landed - vehicle mounting system it!
Now M870 run outDrag racing law enforcementJagged destroy. N Jagged known stronghold coordinates are \ ((x_i, y_i) \ ), each Jagged stronghold in \ (t_i \) will appear Jagged fixed time, but in \ (t_i \) after the meeting for an unknown reason disappear.
M870 want to take away as much Jagged stronghold, but her bike's too old, too fast will explode. So she slightly lower standard, but still requires at least take away \ (k \) Jagged stronghold. Because she has to go outLaw Enforcement, And ask you to help her calculate her at least Biao fast.
(NOTE: The rate can be expressed as \ (\ frac {a {\ sqrt b}} c \), this problem is only required output \ (a, b, c \ ))
input format
of the first row two positive integers, respectively \ (n, k \).
Next n lines of three integers, respectively, \ (t_i, x_i, y_i \ ).
Output Format
line three integers, respectively, in the question \ (a, b, c \ ).
