抄题解.jpg 完全完全不会啊,这道题简直太神了 不过抄题解可真开心 首先这道题目保证了每一个位置上的数都是不同的,那么就能得到第一种判断不合法的方式 如果两个区间的最小值一样,但是两个区间的交集为空集,那么就是不合法的 因为最小值肯定来自于同一个位置 之后就是第二种情况 上面那两个红色区间的最小值是\(4\),但是下面那个被完全包含的绿色区间的最小值是\(3\)这显然非常不合法 但是如果是这个样子呢 显然是可以的,因为那些\(3\)可以来自红色区间以外的位置 就有不行了,因为这个时候\(3\)…

pre 首先注意一下翻译里面并没有提到的一点,也是让我没看懂样例的一点,就是这个长度为 \(n\) 的数组里面的数各不相同. 有很多人用并查集写的这道题,题解里面也有一些用线段树写的,不过我认为我的做法和各位线段树大佬的有些许不同. solution 同样,单调性和二分查找这里不再赘述,直接说给定 \(n\) 个条件,判断他们是否合法. 根据样例我们可以看出,对于同一个数 \(num\) ,如果给定了多个形如 \([l_i,r_i]->num\) 的条件,是可以缩小这个数的范围的. 通俗的说,我…
