The remove( ) algorithm removes elements from the specified range that are equal to val. It returns an iterator to the end of the remaining elements.

The remove_if( ) algorithm removes elements from the specified range for which the predicate pfn is true. It returns an iterator to the end of the remaining elements.

The remove_copy( ) algorithm copies elements from the specified range that are equal to val and puts the result into the sequence pointed to by result. It returns an iterator to the end of the result.

The remove_copy_if( ) algorithm copies elements from the specified range for which the predicate pfn is true and puts the result into the sequence pointed to by result. It returns an iterator to the end of the result.
