其实这是一道折半枚举+Two-Pointers的很好的练手题 //最近CodeForces有点萎,可能会JudgementError,但已经评测过了,能AC,多交几次应该可以 #include <cstdio> #include <algorithm> using std::max; using std::sort; const int N = 40, K = 19; int n, m, k, ans, totx, toty; long long a[N]...
Two pointers is really an easy and effective technique that is typically used for searching pairs in a sorted array. Given a sorted array A (sorted in ascending order), having N integers, find if there exists any pair of elements (A[i], A[j]) such that their sum is equal to X. Il...

具体来说,咱们枚举右端点 \(r\),那么满足 \([l,r]\) 中不存在重复的数值的 \(l\) 显然组成了一段连续的区间,且这个区间的右端点就是 \(r\),因此可以在枚举右端点的同时 two pointers 找出满足“\([l,r]\) 中不存在重复的数值”的最大的 \(l\),设为 \(l'\) 这样我们左端点只用在 \([l'...
