hi @divyanshinegi2003_987b3f0f92dd8c0c,
Here dec part length is 0,
the question says that you need to check if the the whole array can be partitioned somewhere such that initial numbers are increasing and remaining are decreasing

eg 1 2 3 4 9 8 7 6 can be divided into 1 2 3 4 5 9 (increasing) and 8 7 6 (decreasing)

for implementation difficulties check this I’ve commented properly https://ide.codingblocks.com/s/656052

so,the given test case must be false as 1,2,3,4,5 is only increasing

#4

No path can have 0 lenght also but a not a mix of 2 @divyanshinegi2003_987b3f0f92dd8c0c
