remove
Syntax:
  #include <list>
  void remove( const TYPE &val );

The function remove() removes all elements that are equal to val from the list.

For example, the following code creates a list of the first 10 characters of the alphabet, then uses remove() to remove the letter 'E' from the list:

   // Create a list that has the first 10 letters of the alphabet
   list<char> charList;
   for( int i=0; i < 10; i++ )
     charList.push_front( i + 65 );
   // Remove all instances of 'E'
   charList.remove( 'E' );              

Remove runs in linear time.
