struct remove
{

};
Returns a new sequence that contains all elements from [begin<Sequence>::type, end<Sequence>::type) range except those that are identical to T.
[Note: This wording applies to a no-inserter version(s) of the algorithm. See the Expression semantics subsection for a precise specification of the algorithm's details in all cases — end note]

| Parameter | Requirement | Description |
|---|---|---|
| Sequence | Forward Sequence | An original sequence. |
| T | Any type | A type to be removed. |
| In | Inserter | An inserter. |
The semantics of an expression are defined only where they differ from, or are not defined in Reversible Algorithm.
For any Forward Sequence s, an Inserter in, and arbitrary type x:
typedef remove<s,x,in>::type r;
| Return type: | A type. |
|---|---|
| Semantics: | Equivalent to typedef remove_if< s,is_same<_,x>,in >::type r; |
Linear. Performs exactly size<s>::value comparisons for equality, and at most size<s>::value insertions.
