A. Parallelepiped 枚举其中一边,计算其他两条边. B. Array 模拟. C. Bracket Sequence 栈. D. Two Strings \(pre[i]\)表示第i个参与匹配的最长前缀. \(suf[i]\)表示\([i,n]\)能匹配的最大后缀,可以不包括位置i. 如果存在\(pre[i]==0\ or\ pre[i]+suf[i+1]<m\),说明位置i不能够拼成串\(t\). \(pre[i]\):如果\(i\)匹配了长度\(pre[i]\),那么所有位置…

A.Parallelepiped 题意:给一个六面体三面的面积,求12条边的长度和. 题解:因为都是整数,设边长分别为a,b,c,面积为xyz,那么可设x=a*b,y=b*c,z=c*a,简单解方程就可以了. #include <iostream> #include <math.h> using namespace std; int main() { int a, b, c; int x, y, z; while (cin >> x >> y >>…
