Given two sets of integers, the similarity of the sets is defined to be Nc/Nt×100%, where Nc is the number of distinct common numbers shared by the two sets, and Nt is the total number of
题目及O( n l o g 2 n nlog_2n nlog2n)做法 分析 其实我们也可以用O(n)来做,首先来个桶排。 再用一个单调队列存下两个最小值,不断更新。 代码 #include <cstdio>#include <cctype>using namespace std;short t[20001],l,r,min[2],n,head; int a[30001],
Given two sets of integers, the similarity of the sets is defined to be N c / N t × 100 N_c/N_t ×100% Nc/Nt×100, where N c N_c Nc is the number of distinct common numbers shared by the two sets,
