Problem Description I have a very simple problem for you. Given two integers A and B, your job is to calculate the Sum of A + B.   Input The first line of the input contains an integer T(1<=T<=20) which means the number of test cases. Then T lines f…

A*B Problem II 时间限制:1000 ms  |  内存限制:65535 KB 难度:1   描述 ACM的C++同学有好多作业要做,最头痛莫过于线性代数了,因为每次做到矩阵相乘的时候,大量的乘法都会把他搞乱,所以他想请你写个程序帮他检验一下计算结果是否正确.   输入 有多组测试数据,每行给出一组m,n,k(0<m,n,k<=50).m,n,k表示两个矩阵的大小,其中:矩阵A:m行n列.矩阵B:n行k列.接下来给出m*n个数表示矩阵A和n*k个数表示矩阵B,对于每个数s,0<…

题意:就是求a+b (a,b都不超过1000位) 思路:用数组存储 第一道大数的题目,虽然很水,纪念一下! 代码: #include<cstdio> #include<cstring> int main(){ int t,lena,lenb,i,j,sum,testcase=0; char a[1024],b[1024]; char c[1024];//存 a+b int co;//进位 scanf("%d",&t); int tt=t; while(t…

[BZOJ2998]Problem A(动态规划) 题面 BZOJ 题解 一个人的成绩范围可以确定为一个区间 这样就变成了 选择若干区间,不重合, 每个区间有个权值,求最大权值和 这样就可直接\(dp\)了 #include<iostream> #include<cstdio> #include<cstdlib> #include<cstring> #include<cmath> #include<algorithm> #includ…

[Luogu1414]又是毕业季II(数论) 题面 题目背景 "叮铃铃铃",随着高考最后一科结考铃声的敲响,三年青春时光顿时凝固于此刻.毕业的欣喜怎敌那离别的不舍,憧憬着未来仍毋忘逝去的歌.1000多个日夜的欢笑和泪水,全凝聚在毕业晚会上,相信,这一定是一生最难忘的时刻! 题目描述 彩排了一次,老师不太满意.当然啦,取每位同学的号数来找最大公约数显然不太合理.于是老师给每位同学评了一个能力值.于是现在问题变为,从n个学生中挑出k个人使得他们的默契程度(即能力值的最大公约数)最大.但因为…

[BZOJ2302][HAOI2011]Problem C(动态规划) 题面 BZOJ 洛谷 题解 首先如果\(m=0\)即没有特殊限制的话,那么就和这道题目基本上是一样的. 然而这题也有属于这题的性质,发现座位数和人数是一样的. 那么一种方案是合法的,当且仅当编号小于等于这个位置\(i\)的人数不小于\(i\). 首先把不合法直接判掉,考虑存在合法状态的情况. 设\(f[i][j]\)表示有\(j\)个人的编号小于等于\(i\)的方案数.显然\(i\le j\). 考虑如何转移,我们显然从\(…
