struct[reverse\_remove\_if](./reverse-remove-if.html){

Returns a new sequence that contains all the elements from [begin<Sequence>::type, end<Sequence>::type) range in reverse order except those that satisfy the predicate Pred.
[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]
#include <[boost/mpl/remove\_if.hpp](../../../../boost/mpl/remove_if.hpp)>
| Parameter | Requirement | Description |
|---|---|---|
| Sequence | Forward Sequence | An original sequence. |
| Pred | Unary Lambda Expression | A removal condition. |
| 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, and an Inserter in, and an unary Lambda Expression pred:
typedef[reverse\_remove\_if](./reverse-remove-if.html)<s,pred,in>::type r;
| Return type: |
A type.
| | Semantics: |
Equivalent to
typedef[lambda](./lambda.html)<pred>::type p;
typedef[lambda](./lambda.html)<in::operation>::type op;

Linear. Performs exactly size<s>::value applications of pred, and at most size<s>::value insertions.
