【CF1635F】 Closest Pair 题解

CF 传送门：CF1635F 找性质规律 + 单调栈 + 线段树 Solution 1 考场上想出了把那些点对扔进单调队列然后乱搞的做法。发现对于一个询问区间，如果想要直接都扔进单调队列然后从中找到带权距离最小值复杂度仍然很高。换句话说，我们无法直接得到区间最优解。那不妨来试着求解单点最优解，

cf522 D. Closest Equals（st表、区间）

题意：给定数组，m次查询 L,R，输出区间内相等数对的最小距离。若L到R中没有相等数则输出-1 $n,m\le 5e5, |a_i|\le 1e9$ 思路：按相等的数找出不超过n-1个区间，问题变为找 $[L,R]$ 中的最小区间。若区间A包含区间B，则区间B更优，区间A就没有存在的必要了。最终得到一列左端点严格递增，
