I want you to analyze complex options positions.

Given an underlying QQQ, I want to see if the bear put spread legs are identical to the SHORT bull put spread legs. Do this step by step.

First, figure out what legs would a QQQ bear put spread for a particular expiry date and strike price spreads be composed of.

Then, figure out what legs SHORT a QQQ bull put spread for the SAME expiry dates and strike price points are.

Next, tell me if LONG bear put spread and SHORT bull put spread of same duration and spread price points are one and the same position.
