Description A numeric sequence of ai is ordered if a1 < a2 < ... < aN. Let the subsequence of the given numeric sequence (a1, a2, ..., aN) be any sequence (ai1, ai2, ..., aiK), where 1 <= i1 < i2 < ... < iK <= N. For example, seq
Given an unsorted array of integers, find the number of longest increasing subsequence. Example 1: Input: [1,3,5,4,7] Output: 2 Explanation: The two longest increasing subsequence are [1, 3, 4, 7] and [1, 3, 5, 7]. Example 2: Input: [2,2,2,2,2] Outpu

Racing Gems You are playing a racing game. Your character starts at the x axis (y = 0) and proceeds up the race track, which has a boundary at the line x = 0 and another at x = w. You may start the race at any horizontal position you
Given an unsorted array of integers, find the length of longest increasing subsequence. For example,Given [10, 9, 2, 5, 3, 7, 101, 18],The longest increasing subsequence is [2, 3, 7, 101], therefore the length is 4. Note that there may be more than o
最长递增子序列是动态规划中最经典的问题之一,我们从讨论这个问题开始,循序渐进的了解动态规划的相关知识要点. 在一个已知的序列 {a1, a 2,...an}中,取出若干数组成新的序列{ai1, ai 2,...aim},其中下标 i1.i2…im保持递增,即新数列中的各个数之间依旧保持原数列中的先后顺序,那么我们称新的序列{ai1, ai 2,...aim}为原序列的一个子序列.若在子序列中,当下标 ix > iy时,aix > aiy,那么我们称这个子序列为原序列的一个递增子序列.最长递增子
Wavio Sequence My Tags (Edit) Source : UVA Time limit : 1 sec Memory limit : 32 M Submitted : 296, Accepted : 123 Wavio is a sequence of integers. It has some interesting properties. Wavio is of odd length i.e. L = 2 * n + 1. The first (n+1) integers
