Gym 101246H ``North-East''（LIS）

http://codeforces.com/gym/101246/problem/H 题意: 给出n个点的坐标,现在有一个乐队,他可以从任一点出发,但是只能往右上方走(包括右方和上方),要经过尽量多的点.输出它可能经过的点和一定会经过的点. 思路: 分析一下第一个案例,在坐标图上画出来,可以发现,他最多可以经过4个点,有两种方法可以走. 观察一下,就可以发现这道题目就是要我们求一个LIS. 首先,对输入数据排一下顺序,x小的排前,相等时则将y大的优先排前面. 用二分法求LIS,这样在d数组中就可…

java简单的二分法排序

二分法排序的思路:数据元素要按顺序排列,对于给定值 x,从序列的中间位置开始比较,如果当前位置值等于 x,则查找成功:若 x 小于当前位置值,则在数列的前半段中查找:若 x 大于当前位置值则在数列的后半段中继续查找,直到找到为止. 细节: 1.二分法查找,前提是数组必须进行顺序排序,否则查找无法进行: 2.数组中元素的值不可以重复: 3.注意if语句的判定方法及处理语句. 代码如下:当min>max时说明找不到,因为元素重合,min和max代表元素下标.通过下标取值来比较,来查找. clas…
