Defined in header <algorithm>
template< class InputIt1, class InputIt2 > std::pair<InputIt1,InputIt2>     mismatch( InputIt1 first1,               InputIt1 last1,               InputIt2 first2 );	(1)
template< class InputIt1, class InputIt2, class BinaryPredicate > std::pair<InputIt1,InputIt2>     mismatch( InputIt1 first1,               InputIt1 last1,               InputIt2 first2,               BinaryPredicate p );	(2)

Devuelve el par desajuste primero de elementos de dos rangos: uno definido por [first1, last1) y otro a partir de first2. La primera versión de la función utiliza operator== para comparar los elementos, la segunda versión utiliza el predicado binario dado p .

Original:

Returns the first mismatching pair of elements from two ranges: one defined by [first1, last1) and another starting at first2. The first version of the function uses operator== to compare the elements, the second version uses the given binary predicate p.

Parámetros

first1, last1	-	el primer rango de los elementos Original: the first range of the elements The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions.
first2	-	el comienzo de la segunda gama de los elementos Original: the beginning of the second range of the elements The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions.
p	-	binary predicate which returns ​true if the elements should be treated as equal. The signature of the predicate function should be equivalent to the following:  bool pred(const Type1 &a, const Type2 &b); The signature does not need to have const &, but the function must not modify the objects passed to it. The types  Type1 and  Type2 must be such that objects of types InputIt1 and InputIt2 can be dereferenced and then implicitly converted to  Type1 and  Type2 respectively. ​
Type requirements
- InputIt1 must meet the requirements of InputIterator.
- InputIt2 must meet the requirements of InputIterator.
- OutputIt must meet the requirements of OutputIterator.

Valor de retorno

std::pair con los iteradores para los dos primeros elementos no equivalentes, o, si no hay elementos diferentes encontrado, con par last1 y el iterador correspondiente de la gama de segundos .

Original:

std::pair with iterators to the first two non-equivalent elements, or, if no different elements found, pair with last1 and the corresponding iterator from the second range.

A lo sumo last1 - first1 aplicaciones del predicado

Original:

Posible implementación

First version
template<class InputIt1, class InputIt2> std::pair<InputIt1, InputIt2> mismatch(InputIt1 first1, InputIt1 last1, InputIt2 first2) { while (first1 != last1 && *first1 == *first2) { ++first1, ++first2; } return std::make_pair(first1, first2); }
Second version
template<class InputIt1, class InputIt2, class BinaryPredicate> std::pair<InputIt1, InputIt2> mismatch(InputIt1 first1, InputIt1 last1, InputIt2 first2, BinaryPredicate p) { while (first1 != last1 && p(*first1, *first2)) { ++first1, ++first2; } return std::make_pair(first1, first2); }

Ejemplo

Este programa determina la subcadena más larga de la que se encuentra simultáneamente en el mismo comienzo de la cadena dada y en el final de la misma, en orden inverso (que posiblemente se superponen)

Original:

This program determines the the longest substring that is simultaneously found at the very beginning of the given string and at the very end of it, in reverse order (possibly overlapping)
