C/C++中的upper_bound和lower_bound函数用于二分查找，在有序区间内查找特定值的位置。对于upper_bound函数，它返回的是第一个大于查找值的指针，即返回指向被查找值>查找值的最小指针；而对于lower_bound函数，则返回的是第一个大于等于查找值的指针，即返回指向被查找值>=查找值的最小指针。这两个...

对于upper_bound来说，返回的是被查序列中第一个大于查找值的指针，也就是返回指向被查值>查找值的最小指针，lower_bound则是返回的是被查序列中第一个大于等于查找值的指针，也就是返回指向被查值>=查找值的最小指针。不过除此之外，这两个函数还分别有一个重载函数，可以接受第四个参数。如果第四个...
set::upper_bound()是C++ STL中的内置函数,该函数返回一个迭代器,该迭代器指向刚好大于k的下一个元素。如果参数中传递的 key 超过了容器中的最大 key ,则迭代器将返回指向设置容器中最后一个元素的下一个元素(可以使用set end()函数标识)。 用法: ...
如果加上了等号,lower和upper两个函数功能就刚好反过来了: bool cmp(int a,int b) { return a<=b; } int main() { int a[]={0,1,2,2,3}; printf("%d\n",lower_bound(a,a+5,2,cmp)-a); printf("%d\n",upper_bound(a,a+5,2,cmp)-a); return 0 ; } 结果是4 2...
