Hi,

I've a random list of distinct integers as:

1 8 90 1 8 10 11 12 9 5 4 2

I want to find a series of ordered numbers (ascending or descending) with each series having length >3.

E.g.

1 < 8 < 90 has a strict order but this will not be returned since its length is <=3

But 1 < 8 < 10 < 11 < 12 will be returned since it has a strict order and has length = 5.

Similarly 9 > 5 > 4 > 2 will also be returned.

Could anyone please suggest an ways to implement this?

Thanks,
