Table 102 — Associative container requirements (in addition to container) (continued) Expression Return type Assertion/note pre-/post-condition Complexity … a.erase(q1, q2) iterator erases all the elements in the range [q1,q2). Returns q2. log(a.size()) + N where N has the value distance(q1, q2). …
