Function erase_nth

Function erase_nth_copy

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

Synopsis

// In header: <boost/algorithm/string/erase.hpp>


template<typename OutputIteratorT, typename Range1T, typename Range2T> 
  OutputIteratorT 
  erase_nth_copy(OutputIteratorT Output, const Range1T & Input, 
                 const Range2T & Search, int Nth);
template<typename SequenceT, typename RangeT> 
  SequenceT erase_nth_copy(const SequenceT & Input, const RangeT & Search, 
                           int Nth);

Description

Remove the Nth occurrence 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.

	Note
	The second variant of this function provides the strong exception-safety guarantee

Parameters:

`Input`	An input string
`Nth`	An index of the match to be replaced. The index is 0-based. For negative N, matches are counted from the end of string.
`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
