Function erase_nth_copy

boost::algorithm::erase_nth_copy — Erase nth algorithm.

Synopsis

template<typename OutputIteratorT, typename Collection1T, 
         typename Collection2T> 
  OutputIteratorT 
  erase_nth_copy(OutputIteratorT Output, const Collection1T & Input, 
                 const Collection2T & Search, unsigned int Nth);
template<typename SequenceT, typename CollectionT> 
  SequenceT erase_nth_copy(const SequenceT & Input, 
                           const CollectionT & Search, unsigned int Nth);

Description

Remove the Nth occurence of the substring in the input. The result is a modified copy of the input. It is returned as a sequence or copied to the output iterator.

Parameters

Input

An input string

Nth

An index of the match to be replaced. The index is 0-based.

Output

An output iterator to which the result will be copied

Search

A substring to be searched for

Returns: An output iterator pointing just after the last inserted character or a modified copy of the input
Notes: The second variant of this function provides the strong exception-safety guarantee
