描述 You are given a sequence S of parentheses. You are asked to insert into S as few parentheses as possible so that the resulting sequence T is well matched. It's not difficult. But can you tell how many different T you can get? Assume S = ()), you c…

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…

Given an unsorted array of integers, find the length of the longest consecutive elements sequence. For example, Given [100, 4, 200, 1, 3, 2], The longest consecutive elements sequence is [1, 2, 3, 4]. Return its length: 4. Your algorithm should run i…

Given a binary tree, find the length of the longest consecutive sequence path (连续的路径,不是从小到大). 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 ne…
