题意:一个由n个数组成的序列(序列元素的范围是[0, n]).求最长前缀 j .使得在这个前缀 j 中对于随意的数 i1 < i2.都满足随意的 m <= j.i1 在前 m 个数里出现的次数 >= i2 在前 m 个数里出现的次数 - k (1 ≤ n ≤ 200 000, 0 ≤ k ≤ 200 000). 题目链接:http://acdream.info/problem?pid=1427 -->>第一个前缀 j 不满足.那么后面的前缀一定不满足(由于前缀 j 不满足).…

The set [1,2,3,-,n] contains a total of n! unique permutations. By listing and labeling all of the permutations in order,We get the following sequence (ie, for n = 3): "123" "132" "213" "231" "312" "3…

Check whether the original sequence org can be uniquely reconstructed from the sequences in seqs. The org sequence is a permutation of the integers from 1 to n, with 1 ≤ n ≤ 104. Reconstruction means building a shortest common supersequence of the se…

Given a binary tree, find the length of the longest consecutive sequence path. The path refers to any sequence of nodes from some starting node to any node in the tree along the parent-child connections. The longest consecutive path need to be from p…
