以下是使用密钥来使用std::binary_search的示例代码: 代码语言:cpp 复制 #include <iostream> #include <vector> #include <algorithm> int main() { std::vector<int> nums = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; int key = 6; // 使用std::binary_
二分查找(Binary Search)是一种在有序数组中查找某一特定元素的搜索算法。搜索过程从数组的中间元素开始,如果中间元素正好是要查找的元素,则搜索过程结束;如果某一特定元素大于或者小于中间元素,则在数组大于或小于中间元素的那一半中查找,而且跟开始一样从中间元素开始比较。如果在某一步骤数组为空,则代表找不到。
rather than logarithmic, and is still substantially slower than the binary vector search. Counting nodes back and forth in the list still hurts substantially, even if we save a lot by doing only a

参照参数类型的改动,依葫芦画瓢地修改binary_search为: std::optional<int> binary_search(const std::vector<int> &list, int item) { size_t low{0}; size_t high{list.size() - 1}; while (low <= high) { auto mid = (low + high); ...
