[first, last) 的某些元素 elem 使得无法通过 bool(elem < value) 得出!bool(value < elem)。 [first, last) 的元素 elem 没有按表达式 bool(elem < value) 和!bool(value < elem) 划分。 (C++20 前) 等价于 std::binary_search(first, last, value, std::less{})。 (C++20 起)2...
In this article, we are going to see C++ STL function binary_search() which uses the standard binary search algorithm to search an element within a range.
and follow the links from one node to the next, checking them one at a time. Unlike with array subscripting, there is no way to compute the location of a list node directly from knowing its numerical position in the list. So how is it that you can do a binary_search of a std::...
bool found = std::binary_search(vec.begin(), vec.end(), target); std::cout << std::boolalpha << found << std::endl; // true return 0; } 下载 运行代码 4.使用 std::any_of 功能 这std::any_of 如果谓词对指定范围内的任何元素返回 true,则算法返回 true。要检查某个项目是否存在于Vec...
Binary search(operating on partitioned/sorted ranges): lower_bound Return iterator to lower bound (function template ) upper_bound Return iterator to upper bound (function template ) equal_range
std::search在头文件<algorithm>中定义,用于查找满足另一个序列的条件(如果未定义此谓词,则等于)的子序列。 它在序列[first1,last1)中搜索由[first2,last2)定义的子序列的第一个匹配项,然后将一个迭代器返回到该匹配项的第一个元素,如果没有找到匹配项,则返回last1。

Thank you for all of your responses, with your help I was able to figure out my mistakes and improve upon my code. Switching to using two vectors instead of one really helped. Also, I improved my code further by switching to binary_search() instead of find() because the program could ...
