题意: 一个炉子烤鸡,炉子打开的时候一共$T$分钟可以烤完,关闭的时候一共$2T$分钟可以烤完,炉子每$K$分钟自动关闭,厨师每$D$分钟回来检查,打开炉子 问多长时间烤完.. 题解: 用整数写比较稳妥.. 显然,整个过程是呈周期性的. $K>D , t_r = D*(\left \lfloor\frac{K}{D} \right \rfloor +1)  $ $K<=D,  t_r =D$ 将总时间$T*2$,那每个周期提供的完成度 $C=K+D$ 答案就可以出来了.. 输出的时候除以二 判…

题意:给定两个速度,一个一初速度,一个末速度,然后给定 t 秒时间,还每秒速度最多变化多少,让你求最长距离. 析:其实这个题很水的,看一遍就知道怎么做了,很明显就是先从末速度开始算起,然后倒着推. 代码如下: #include <bits/stdc++.h> using namespace std; typedef long long LL; const int maxn = 1e5 + 5; const int INF = 0x3f3f3f3f; vector<int> ans;…
