Bitonic Sequence
A sequence which has at most one local minimum or
maximum
When you break a bitonic sequence at the minimum or
maximum you get two sorted sequences, one ascending and
the other descending
Examples: 1,2,3,4,5,6,7,8 2,5,8,10,7,4,3,1
9,8,5,3,6,10,11,12
splitting the second sequence at 10 gives us 2,5,8,10 and 7,4,3,1 which
are sequences in ascending and descending order respectively
In the third example, the minimum is 3 and splitting the sequence at
3 gives us 9, 8, 5, 3 and 6, 10, 11, 12 which are sequences in descending
and ascending order respectively
