#include "stdio.h" int main(int argc, char const *argv[]) { int n; //freopen("input.txt","r",stdin); scanf("%d",&n); while(n--) { char a; int b,c,d; char ch=getchar(); scanf("%c%d",&a,&b); c=a; if(a>='A'&&a<='Z') d=c-64; if(a>='a'&&a<='z') d=96-c; printf("%d\n",b+d); } return 0; }
//最优代码 #include<stdio.h> main() { int x,n; scanf("%d",&x); while(x--) { getchar(); char c; scanf("%c %d",&c,&n); if(c>=65&&c<=90) c=c-64; else c=0-(c-96); n=c+n; printf("%d\n",n); } }
