矩阵乘法,顾名思义矩阵与矩阵相乘, 两矩阵可相乘的前提:第一个矩阵的行与第二个矩阵的列相等 相乘原则: a b * A B = a*A+b*C a*c+b*D c d C D = c*A+d*C c*A+d*C 上代码 struct matrix { ll a[maxn][maxn]; }; matrix matrix_mul(matrix x,matrix y) { matrix temp; ;i<=n;i++) ;j<=n;j++) { tem…
文泽想在埃及做案n次,并且想在最后不用得到惩罚.案件的被分成几种类型.比如说,案件A,当案件A被重复犯两次时,案件A将被认为不是犯罪案件,因此犯案人不用得到惩罚.也就是说,案件A被犯偶数次时,犯案人将不用得到惩罚.又比如案件B,当案件B被犯的次数是5的倍数时,犯案人将不用得到惩罚. 更具体的说,现在知道有c组条件.每组条件包含的信息如下: 1. 案件类型 ti , 2. 底数 mi ,表示该类型案件重复n* mi (n是非负整数)次时,犯案人可以不用得到惩罚. 对于同一种案件,他的条件可能会…
