Hi shreya
in this problem you have to basically consider 4 cases

the sequence can be either monotonically increasing
the sequence can be either monotonically decreasing
it can be either first increasing then decreasing
it can be either first decreasing then increasing.
if any of the case is true then answer is “yes”
try working upon this.

Hello Aastha, I was also working on the same problem and was working with the same understanding that you mentioned. However in the code sample when I unlocked the editorial they have just considered either the sequence is monotnically increasing or monotonically decreasing. Can you please help me out with how to handle the other two conditions.
Regards and Thank You
Akshay
