A sequence is called bitonic if it first strictly increases and immediately strictly decreases. For example, [100, 200, 100), [100, 200, 300, 50), [100, 200, 50, -100) are bitonic since they first strictly increase and then strictly decrease, whereas [1, 2, 2, 11], (1.2, 3), and [3, 2, 1) are not. Note that a bitonic sequence must have at least three values.
a) True
b) False
