题目链接:http://acm.split.hdu.edu.cn/showproblem.php?pid=5037 题解:为了让放的石头有意义肯定是没l+1的距离放2个也就是说假设现在位置为pos那么在pos+1放一个在pos+l+1放一个这样就需要跳两次.于是这题要考虑的就是当前位置和前一个石头放的位置因为如果前一个石头的位置到a[i]的距离小于等于l那么当前位置就不能被走到.所以就拿l+1的距离来贪心. #include <iostream> #include <cstring>…

题意比较难懂,一只青蛙过河,它最多一次跳L米,现在河中有石头,距离不等,上帝可以往里加石头,青蛙非常聪明,它一定会选择跳的次数最少的路径.问怎么添加石头能让青蛙最多的次数.输出青蛙跳的最多的次数. 考虑对于长度L+1,上帝一定会让青蛙跳两次.那么只需要尽可能的构造L+1就行了.那么就需要求多少个L+1就行了.还有就是需要记录上一次跳的距离,如果上一次跳的距离加上这次的距离小于L+1的话,那么上次一定会跳到当前这个点,而不是跳到上次那个点,所以更新一下上次的距离.也就是这两种情况: 1)上一步pr…

开始就觉得有思路,结果越敲越麻烦...  题意很简单,就是说一个青蛙从0点跳到m点,最多可以跳l的长度,原有石头n个(都仅表示一个点).但是可能跳不过去,所以你是上帝,可以随便在哪儿添加石头,你的策略是让青蛙跳过去的次数最多,但是你添加了石头后,青蛙会选择最少的次数跳过去,问青蛙跳的次数最多是多少. 原有石头与现在的距离不大于l,就找最远的那个可以跳的石头跳过去.接下来就是主要解决现在的位置与接下来的一块石头的距离大于l的情况了.模拟:上帝开始放石头,要让青蛙一定是这次跳这块石头(在上次不能跳)…
