# So no one is even questioning why a envelope could not be rotated ?

• say given is [3, 2] [3, 4 ] after rotate [3, 4] -> [4, 3] then we can put [3, 2] into [4, 3]

• Yes, I was wondering if we need to consider this scenario... Maybe, we need first reorder the input envelopes so that envelopes[0] >= envelopes[1] ?

• I think envelopes traditionally have a single opening which gives them an orientation.

• @billy11 How does that matter, though?

• @StefanPochmann If you have an orientation then the length and width are topographically defined.

Allowing rotation assumes:

1. Width and height are the same units
2. Rotation doesn't change the properties of the envelopes. For example: if they have an opening at the top rotation removes the likelihood of constant time insert and removal.

• @billy11

1. If that weren't the case, it should be stated. It's definitely legitimate to assume.
2. The question doesn't care about such times.
