@singh.balpreet965 According to the question, the following possibilities may arise after splitting a sequence into two sequences:

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

For input:
6
3
2
1

2
3

Output: true
