There are n trees planted in lxhgww's garden. You can assume that these trees are planted along the X-axis, and the coordinate of ith tree is xi. But in recent days, lxhgww wants to move some of the trees to make them look more beautiful. lxhgww will…

题目链接:bnu 34982 Beautiful Garden 题目大意:给定一个长度为n的序列,问说最少移动多少点,使得序列成等差序列,点的位置能够为小数. 解题思路:算是纯暴力吧.枚举等差的起始和中间一点,由于要求定中间一点的位置.所以这一步是o(n3);然后用o(n)的算法确定说须要移动几个来保证序列等差. #include <cstdio> #include <cstring> #include <vector> #include <algorithm&g…

BNUOJ 34982 Beautiful Garden 题目地址:BNUOJ 34982 题意:  看错题意纠结了好久... 在坐标轴上有一些树,如今要又一次排列这些树,使得相邻的树之间间距相等.  刚開始瞄了一眼以为是求最短的移动距离...后来发现是求最少去移动的树的数量. 分析:  刚開始想错了,以为随意取两棵树,作为相邻的两棵树即可了,吃了好多个wa后,发现这个有问题,由于考虑里面三棵树为终于序列中的三个.那么就有可能推断不出来.  于是想了新的方法,枚举两棵树后,再枚举中间有几棵树,在…

题意:给你坐标和n个点,求最少移动的点使得n个点成等差数列 思路:既然要成等差数列,那么最起码有两个点是不动的,然后枚举这两个点中间的点的个数,近期水的要死,看了队友的代码做的 #include <iostream> #include <cstdio> #include <cstring> #include <algorithm> #include <cstdlib> #include <cmath> using namespace…
