[FEA]: add thrust::mismatch overloads with last2 parameter

[bernhardmgruber]

Thrust only implements the mismatch overloads taking an unbounded second range: InputIt1 first1, InputIt1 last1, InputIt2 first2. However, since C++14 there are also overloads where we can specify the end of the second range: InputIt1 first1, InputIt1 last1, InputIt2 first2, InputIt2 last2. We should provide these overloads.

// Overload without a binary predicate for bounded second range

template <typename InputIt1, typename InputIt2>
__host__ __device__
std::pair<InputIt1, InputIt2>
mismatch(InputIt1 first1, InputIt1 last1, InputIt2 first2, InputIt2 last2)
{
    while (first1 != last1 && first2 != last2 && *first1 == *first2) {
        ++first1;
        ++first2;
    }
    return std::make_pair(first1, first2);
}

// Overload with a binary predicate for bounded second range
template <typename InputIt1, typename InputIt2, typename BinaryPredicate>
__host__ __device__
std::pair<InputIt1, InputIt2>
mismatch(InputIt1 first1, InputIt1 last1, InputIt2 first2, InputIt2 last2, BinaryPredicate p)
{
    while (first1 != last1 && first2 != last2 && p(*first1, *first2)) {
        ++first1;
        ++first2;
    }
    return std::make_pair(first1, first2);
}

How about this?

Add mismatch overloads with bounded second range

This commit implements two new overloads for the mismatch algorithm,
allowing users to specify both the beginning and end of the second range.
These overloads work with and without a custom binary predicate.
This change brings the implementation in line with the C++14 standard,
and is consistent with the overloads provided by the standard library.
