Nearest Angle

CodeChefOpen on judge ↗

You are given a sequence of positive integers $A_1, A_2, \ldots, A_N$. You must choose three elements $A_x, A_y, A_z$ ($x$, $y$, $z$ should be pairwise distinct) such that there is a non-degenerate triangle $\mathsf{XYZ}$ with the following properties: - $|\mathsf{XY}| = A_z$, $|\mathsf{XZ}| = A_y$, $|\mathsf{YZ}| = A_x$ - the angle $|\angle \mathsf{YXZ}| = \theta$ satisfies $\cos\theta \ge P/Q$
