NYOJ 121 另类乘法
开始把题意看错了,把数组多开了100000000倍,结果直接运行不了,运行框都不出来了...⊙﹏⊙b汗
附ac代码:
#include <stdio.h> #include <string.h> #define MAX 11 char a[MAX], b[MAX]; int main(){ int t; long long s; scanf("%d", &t); while(t-- && scanf("%s%s", a, b)){ s = 0; int m = strlen(a), n = strlen(b); for(int i = 0; i != m; ++i){ if(a[i] == '0') continue; for(int j = 0; j != n; ++j){ if(b[j] == '0') continue; s += (a[i] - '0') * (b[j] - '0'); } } printf("%lld\n", s); } return 0; }
