题意:棋牌游戏如今,一种被称为“超级跳!跳!跳!“HDU是非常流行的.也许你是个好孩子,这个游戏知之甚少,所以我介绍给你吧. 可以玩游戏由两个或两个以上的球员 .它由一个棋盘(棋盘)和一些棋子(棋子),所有的棋子标记的正整数或“开始”或“结束”.玩家从起始点和终点终于跳进.在跳跃的过程中,玩家将访问路径中的棋子,但每个人都必须从一个棋子跳跃到另一个绝对更大(可以假定启动点是一个最小和终点是一个最大).所有玩家都可以不走回头路.一个跳跃到下一个棋子,也可以去跨越许多的棋子,甚至你可以从起始点到终点…

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…

  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…

题目的意思是给定k个盒子,每个盒子的维度有n dimension 问最多有多少个盒子能够依次嵌套 但是这个嵌套的规则有点特殊,两个盒子,D = (d1,d2,...dn) ,E = (e1,e2...en) 只要盒子D的任意全排列,小于盒子E,那么就说明 盒子D能放入盒子E中,其实就是将两个盒子的维度排序,如果前一个盒子的维度依次小于后一个盒子,那么就说明前一个盒子能放入后一个盒子中 这个题目能够转化为最长递增子序列. 首先将盒子的维度从小到大排序,然后将k个盒子,按照排序后的第一维度从小到大排…

Given an unsorted array of integers, find the length of longest continuous increasing subsequence. Example 1: Input: [1,3,5,4,7] Output: 3 Explanation: The longest continuous increasing subsequence is [1,3,5], its length is 3. Even though [1,3,5,7] i…

先说这题的关键性质:每一个数应该只会计算一次,它有一个最小区间[L,R],即它在这个区间内是最小的,最小区间内任何包含它的子区间都不会大于F(L,R)=(a[L]+...+a[R])*min(a[l]..a[R]),只需要计算一次就可以不再计算其他子区间. 利用这个性质,可以得到这样的做法,如果能知道任意区间的最小值,就能不断递归去删点,就能轻松分割出每个点的最小区间.可以用线段树在O(lgn)复杂度快速得到 区间的最小值及其下标,总时间复杂度就是O(nlgn). 但是,理想是美好的,AC是做不…
