题目地址:http://codeforces.com/contest/435/problem/C /* 题意:给一组公式,一组数据,计算得到一系列的坐标点,画出折线图:) 模拟题:蛮恶心的,不过也简单,依据公式得知折线一定是一上一下的,只要把两个相邻的坐标之间的折线填充就好 注意:坐标有可能为负数,所以移动值y初始化为1000,最后要倒过来输出 详细解释:http://blog.csdn.net/zhb1997/article/details/27877783 */ #include <cstd…

D.E还是很难的.....C不想多说什么... A:提意:给出每一组人的个数,以及一次车载容量,求出最少需要多少次才能载走所有的人. water: http://codeforces.com/contest/435/submission/6741997 B:提意:给出一个数,最多可以交换两个数k次,并且每次只能交换相邻的数,求最大的数是多少. water: 很水的贪心,直接从后往前扫描k位,把最大的数转移到最高位就行了.只不过晚上杀了一晚的后缀数组,木了,搞了半天.. http://codefo…

C好像就是个模拟.D 是个编码复杂度大的,可是好像也就是枚举三角形,我这会儿准备区域赛,尽量找点思维难度大的,所以昨晚A B 还是去做区域赛题吧..... B 也有点意思 贪心 题意:交换相邻两个位的数.然后最多换k次,求最大数 解法,找<=k范围内的最大数.与之交换.右移一位.继续找,直到k用完 //#pragma comment(linker, "/STACK:102400000,102400000") #include <cstdio> #include <…
