Well, when you are querying for a segment say [l,r] and if the maximum position lies in index r or l, then your function should return 1 as the most highest value is present in the extreme ends of the array.
But your function is recurring for more subproblems increasing the overall complexity of the program.
For the test case
1

4

1 2 3 10

instead of going through only [0,3]
your function is computing for
[0 3]
[0 2]
[3 2]
[0 1]
[2 1]
[0 0]
[1 0]
hence increasing the complexity of the program.
