binary_search 检查等价于value的元素是否出现在范围[first,last)中出现。内部一般使用std::lower_bound实现。 函数签名 conststd::vector<int>data{11,12,14,15,15,16};assert(std::binary_search(data.cbegin(),data.cend(),10)==false);assert(std::binary_search(data.cbegin(),data.cend(),11)==tru...
二分查找(Binary Search)法,是在一个有序的集合中查找指定键值的一种方法。假设有一个集合,集合中的元素按照键值从小到大有序。集合中元素的键可以用一个列表list=(x1,x2,...,xn)list=(x1,x2,...,xn)表示,其中xi≤xi+1xi≤xi+1。任务是要查找一个键keykey在这个列表中的位置。
The goal of this project is to translate the wonderful resource http://e-maxx.ru/algo which provides descriptions of many algorithms and data structures especially popular in field of competitive programming. Moreover we want to improve the collected kno
