题面看这里 \(PS\):符号 \([\ \rm P\ ]\) 的意义是:当表达式 \(\rm P\) 为真则取值为 \(1\),为假则取值为 \(0\). 题目大意 给你一个一天有 \(H\)​​​​​​​ 小时.一小时有 \(M\)​​​​​​​​ 分钟的表和一个正整数 \(A\)​,问一天内有多少个整数时刻,使得分针与时针的夹角小于等于 \(\displaystyle\frac{2\pi A}{HM}\)​. 题目分析 易知分针转速 \(w_1=\displaystyle \frac{2\…

大致题意 原题链接 翻译 \(有n个逻辑变量 请你分别对它们赋值 使其满足m个命题\) \(命题有四种格式:\) 单独数字x 表示第x个逻辑变量为真 ! + 数字x 表示第x个逻辑变量为假 若干个数字\(a_1, a_2, ..., a_p\)(不给出个数) -> 数字x 表示前面的a变量全为真 的时候x必定为真 若干个数字\(a_1, a_2, ..., a_p\)(不给出个数) -> ! + 数字x 表示前面的a变量全为真 的时候x必定为假 其中每个命题之间空行 即'\n' 注: 此题含有…
