对于vector: int pos = lower_bound(v.begin(),v.end(),x)-v.begin(); 对于数组: int pos = lower_bound(a,a+n,x)-a; 2.对于递减序列 那么接下来考虑,如果容器中元素是递减的如何查找呢? 可以利用仿函数greater<date_type>()去重新定义比较规则。这样的话对于lowerbound()查找的是容器中第一个小于...

upper_bound( begin,end,num):从数组的begin位置到end-1位置二分查找第一个大于num的数字,找到返回该数字的地址,不存在则返回end。通过返回的地址减去起始地址begin,得到找到数字在数组中的下标。 在从大到小的排序数组中,重载lower_bound()和upper_bound() lower_bound( begin,end,num,greater<type>() ):从...
lower_bound( begin,end,num,greater<type>() )-num,从数组的begin位置到end-1位置二分查找第一个小于或等于num的数字,不存在则返回end-1。 upper_bound( begin,end,num,greater<type>() )-num,从数组的begin位置到end-1位置二分查找第一个小于num的数字,不存在则返回end-1。

approaching the upper bound of the scale. This suggested that most participants in our sample were both doing a large proportion of the household laborandperceived this division of labor to be unfair. Thus, both perceived unfairness and perceived partner dependence are common and important responses...
int l=upper_bound(a,a+4,2)-a; // 输出1 int l=upper_bound(a,a+4,4)-a; //输出 3 } 如果要返回最后⼀个⼩于等于x的位置，直接在上⾯获取的下标-1即可。lower_bound( begin,end,num,greater<type>() )-num，从数组的begin位置到end-1位置⼆分查找第⼀个⼩于或等于num的数...
A version of this model is used in order to estimate heritability of the individual frailty and to calculate the lower bound of human longevity. The limitations of this approach and directions of further research are discussed. 展开 关键词: Survival analysis Bivariate model Quantitative genetics ...

Zero lower bound 1. Introduction A number of contributions to research on monetary policy have suggested that central banks should conduct policy in an asymmetric fashion near zero nominal interest rates. Due to the low opportunity costs of holding cash, there is a lower bound on central banks’...
