Increasing Deccreasing Sequence

#1

This is link for my code .
Please check this code and help me to find out the problem in this code to pass all the test cases.

Why it is showing the Doubt?
Increasing Decreasing sequence
Increasing decreasing sequence
#2

According to the question, the following possibilities may arise after splitting a sequence into two sequences:

-First Sequence is strictly decreasing , 2nd sequence is strictly increasing–> return true
-First Sequence is strictly increasing, 2nd sequence strictly decreases-------> return false
-If one sequence is empty and the other sequence is strictly increasing/decreasing—>return true.

Consider test case:
For input:
6
3
2
1
1
2
3

Now this splits into 2 sequences-- 3 2 1(decreasing) and 1 2 3(increasing)
So Expected Output:
true

Your Ouput:
false

Also for case:
5
5
5
5
5
5

Expected Output:
false

Check and dry run your code with these cases.

#3

After dry run with these cases,for first cases it show correct output but for second case it show wrong output.

I tried to solve this problem since very long time but failed

Please share the code.

#5

Dry run and check.
