It’s quite difficult to point out the bug in your program! Still try this test case

Test Case:
5 4
1 3 3 2 1
Your O/P: 3
Actual O/P: 2

Maybe you are not checking the time for all required combinations in the array! You are missing the combination of 1 on first position and 3 on second position. You only calculated the time of 1 on first position and 3 on third position.

Try this test case:
5 4
