思路:用字符串输入后,把字母转化成对应的数字,再相加
难度:这个也是简单的
代码:
1 #include<stdio.h> 2 int main() 3 { 4 int n,i,a; 5 char s; 6 while(scanf("%d",&n)!=EOF) 7 { 8 getchar(); 9 for(i=0;i<n;i++) 10 { 11 scanf("%c%d",&s,&a); 12 getchar(); 13 if(s>='A'&&s<='Z') 14 printf("%d\n",s-64+a); 15 else printf("%d\n",96-s+a); 16 } 17 } 18 return 0; 19 }
