Reverses the order of the elements in the . std::string reverse_string(std::string &str) { const char*buf = str.c_str(); char *start = const_cast(buf); char *end = start + strlen(buf) - 1; char t; while(start < . std::ranges:: reverse. Constrained algorithms, e.g. ranges::copy, ranges::sort, . 1) Reverses the order of the elements in the range [first,last). Behaves as if applying ranges::iter_swap to every pair of iterators first + i, last - i -1 for each integer i, where 0 ≤ i <(last - first)/2. 2) Same as (1), but uses r as the range, as if using .reverse in c++ stl std::reverse () in C++. reverse () is a predefined function in header file algorithm. It is defined as a template in the above-mentioned header file. It reverses the order of the elements in the range [first, last) of any container. The time complexity is O (n).

この投稿では、C++ でベクトルを反転する方法について説明します。最も簡単な解決策は、`algorithm` ヘッダーで定義されている `std::reverse` 関数を使用することです。この関数は内部で `std::iter_swap` を使用して、指定された範囲の両端の要素を交 .

Complexity. Exactly std:: distance (first, last) / 2 swaps. [] ExceptionThe overload with a template parameter named ExecutionPolicy reports errors as follows: . If execution of a function invoked as part of the algorithm throws an exception and ExecutionPolicy is one of the standard policies, std::terminate is called. For any other ExecutionPolicy, the . I don't see how it is more elegant or advantageous in any way to using std::reverse though. – CashCow. Jan 16, 2012 at 10:45. 20 @CashCow: Well, for one, it's a no-op, it's O(1). Reversing.. not so much. Most of the time, you don't really need a reversed container, you only need to see it as reversed. In fact, I can't think of a situation . Обратный vector в C++. В этом посте мы обсудим, как инвертировать vector в C++. 1. Использование std::reverse функция. Самое простое решение — использовать std::reverse функция, определенная в заголовок.
There's nothing to stop your reverse_iterator loop also using the index as described in multiple other answers. That way you can use the iterator or index as needed in the // do the work part, for minimal extra cost.. size_t index = v.size() - 1; for(std::vector::reverse_iterator rit = v.rbegin(); rit != v.rend(); ++rit, --index) { // . You can reverse the first two elements by using std::reverse(vec.begin(), vec.begin() + 2); but simpler would be std::swap(vec[0], vec[1]); – Neil Kirk. Oct 24, 2014 at 1:01. 1. @user2840454, The end iterator is one past the end because it plays nicely (e.g., the pair easily being able to represent an empty range) – chris. Oct 24, 2014 at 1 .std:: reverse. template void reverse (BidirectionalIterator first, BidirectionalIterator last); Reverse range. Reverses the order of the elements in the range [first,last). The function calls iter_swap to swap the elements to their new locations.
C++ で std::reverse アルゴリズムを使用してベクトル要素を反転する. std::reverse は STL アルゴリズムの一部であり、任意の範囲の要素の順序を逆にするために使用できます。std::reverse アルゴリズムは、最初と最後のペアから始まる 2つの要素を内部的に交換します。이 게시물에서는 C++에서 벡터를 반전시키는 방법에 대해 설명합니다. 가장 간단한 해결책은 `algorithm` 헤더에 정의된 `std::reverse` 함수를 사용하는 것입니다. 이 함수는 주어진 범위의 양쪽 끝에서 요소를 교환하기 위해 내부적으로 `std::iter_swap`을 사용합니다.reverse - cpprefjp C++日本語リファレンス. 最終更新日時 (UTC): 2022年12月27日 15時47分26秒.
