Aadharsh and his modified Biotonic Sequence

Aadharsh is a great coder in CEG. He always solves hard problems in codeforces. He recently solved the question of finding the longest biotonic subsequence in an array of integers. A Bitonic Sequence is a sequence of numbers which is first strictly increasing then after a point strictly decreasing. A Bitonic Point is a point in bitonic sequence before which elements are strictly increasing and aft
