I think that extending space should not be considered, so I wrote O(n) , but I am not sure. what's the answer? 回答1: It depends on the question that was asked. If the question asked for the time required for one insertion, then the answer is O(n) because big-O implies "worst case.

问题 I was suggested using insertUI here and found that it is a great feature. The following code allows to generate control widgets for a single or multiple elements using insertUI , but struck on incorporating removeUI related part. Tried jQuery options to remove inserted UI elements but did not work out.
