This is the problem .
According to the accepted solution of other coders, the following test case gives a "Yes". But, shouldn't it give a "No" ?
6 1 2 1 1 1 1 1 1 6
Any help would be really appreciated.

Note that the non-decreasing and the non-increasing sequences are also considered ladders.Yeah, I understand that.
But the given query is on the range of [1, 6]. In that range, the sequence is [2, 1, 1, 1, 1, 1].
So, it is decreasing, and then non-decreasing/non- increasing. Hence, this doesn't qualify as a ladder.
Because the question says, it should satisfy either of the three criteria:
But, the given is decreasing and then non- decreasing. Hence, it doesn't qualify in either of the three criteria.
"it is decreasing" --> it is non-increasing. Thus point 3 is satisfied.
It is still failing.

Can you tell your approach?
