## 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
