On a plane there is a set of parabolas given by equations in the form y=a⋅x2+b⋅x+c.
Let's consider a point to be located inside a parabola if it located above the parabola in case of positive coefficient a, or below the parabola in case of negative a.

On this figure, the point P is located inside both parabolas, the point Q is inside one of them, and the point R is inside none of them.
You need to find any point that is located inside all parabolas. It is guaranteed that such point exists.
The first line contains a single integer n (1≤n≤100,000) --- the number of parabolas.
Each of the next n lines contains three integers a, b, c (∣a∣,∣b∣,∣c∣≤109; a=0), describing a parabola y=a⋅x2+b⋅x+c.
Print two real numbers x and y --- coordinates of a point located inside all parabolas.
The answer is considered correct if there exists a point at distance at most 10−6 from the printed one, which is located strictly inside all parabolas.
