I am unable to understand the question

please explain the question to me?

hey @rishabhtanishaq ,
you are provided with a sequence , now you need to tell that ,
can this sequence be split in 2 sub sequences such that the first sequence is decreasing and the other one is increasing.

I hope this helps.

please explain me the first example?

5
1
2
3
4
5

here there can be two sequences [5 1] and [2 3 4 5] , in this way the first one is decreasing and the other one is increasing .
I hope you understand this,
