https://www.geeksforgeeks.org/upper_bound-in-cpp/ 在有序数组中,找到大于目标值的数据集合中值最小的位置。 upper_bound() is a standard library function in C++ defined in the header . It returns an iterator pointing to the first element in the range [first, last) that is greater than val...
lower_bound upper_bound in cpp upper_bound Returns an iterator pointing to the first element in the range [first,last) which compares greater than val. Return value An iterator to the upper bound position for val in the range. If no element in the range compares greater than val, the fun...

lower_bound和upper_bound的差别只有一个小于号和小于等于号的差别,以下是我的实现: uint32_tlower_bound(intarr[],intlen,intval){intbeg=0;intend=len;intmid;while(beg<end){mid=(beg+end)>>1;if(arr[mid]<val){beg=mid+1;}else{end=mid;}}returnbeg;} uint32_tupper_bound(intarr[],intlen,...

upper_bound performs at most log(last - first) + 1 comparisons.Example// // ul_bound.cpp // #include <vector> #include <algorithm> #include <functional> #include <iostream> using namespace std; int main() { typedef vector<int>::iterator iterator; int d1[11] = {0,1,2,2,3,4,...
upper_bound返回一个迭代器,该迭代器指向[first,last)范围内的第一个元素,该元素的值大于’val’。 CPP // lower_bound and upper_bound in vector #include // for lower_bound, upper_bound and sort #include #include // for vector using namespace std; int main() { int gfg[] = { 5, 6, ...
