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 need to be from parent to chi...
Lookup example in binary tree data structure. The sequence is shown for lookup of 01001111. While this algorithm clearly performs correctly, it exhibits poor performance when implemented on a router system. In a typical implementation, a node is a data structure stored in memory and an edge is...
Given a binary tree, find the length of the longest path where each node in the path has the same value. This path may or may not pass through the root. Note: The length of path between two nodes is represented by the number of edges between them. Example 1: Input: 5 / \ 4 5 ...

The heaviest increasing subsequence (HIS) weight of S is defined as the maximum of w(T) over all increasing subsequence T of S, where w(T) denotes the sum of w(s) over all integers s in T. Any increasing subsequence of S that achieves the HIS weight of S is called an HIS of S...
