Given test case not clear

#1

such that first sequence is strictly decreasing and second is strictly increasing.
according to this line given test case shold print false.

#2

Hello @Aparna,

you don’t have to split the sequence.
what you are required to do is to keep track of whether the sequence is:

  • strictly increasing (entirely) eg. [1,2,3,4]
  • strictly decreasing (entirely) eg. [5,3,2,0]
  • First strictly decreasing than strictly increasing eg. [5,3,1,4,6]

    if yes,
    print true
    else,
    print false

strict function: which do not contain the same number at consecutive positions i.e. same values cannot occur one after other.
example: [1, 1, 2] This is not a strict function as there are two 1 at consecutive locations.

Hint: there should be no decrease in sequence if it once starts increasing i.e. first increasing then decreasing returns false. eg. [2,4,7,3,1] (not accepted)

In the series, you have given, the decreasing sequence is null/empty.
Thus, falling into point 1.

Hope, this would help.
if you still have doubts, feel free to ask.
Give a like if you are satisfied.
