Question

Use python to answer this question

3. Unimodal Sequence
Given n2 1, a sequence of n integers a[0],. . ., a[n-1] is
unimodal if there exists t (with 0 st<n) that satisfies
the following conditions:
• a[0] <...< a[t-1] < a[t]
a[t] > a[t+1] > . . . > a[n=1]
The element a[t] is called the top of the sequence.
For example, the sequence 1, 3, 5, 9, 4, 1 is unimodal,
and its top is 9 (t = 3).
Write a function
get Toplndex_UnimodelSequence that takes a
unimodal sequence & returns the index of the top of
the sequence. The solution must have cost O(log(n)) in
time in the worst case.
