This is the hard version of the problem. The difference is the constraint on the sum of lengths of strings and the number of test cases. You can make hacks only if you solve all versions of this task. You are given a string ss, consisting of lowercas
1.矩阵相加 两个同型矩阵做加法,就是对应的元素相加. #include<iostream> using namespace std; int main(){ int a[3][3]={{1,2,3},{6,5,4},{4,3,2}}; int b[3][3]={{4,3,2},{6,5,4},{1,2,3}}; int c[3][3]={0,0,0,0,0,0,0,0,0}; int i,j; cout<<"Array A:"<<endl; for
