Problem Description
we define f(A) = 1, f(a) = -1, f(B) = 2, f(b) = -2, ... f(Z) = 26, f(z) = -26;
Give you a letter x and a number y , you should output the result of y+f(x).
Give you a letter x and a number y , you should output the result of y+f(x).
Input
On the first line, contains a number T.then T lines follow, each line is a case.each case contains a letter and a number.
Output
for each case, you should the result of y+f(x) on a line.
Sample Input
6 R 1 P 2 G 3 r 1 p 2 g 3
Sample Output
19 18 10 -17 -14 -4
#include <stdio.h>
main()
{
int i,y,t;
char x;
scanf("%d",&t);
for(i=0;i<t;)
{
scanf("%c%d",&x,&y);
if((x>=65) && (x<=90))
printf("%d\n",y+x-'A'+1,i++);
if((x>=97) && (x<=122))
printf("%d\n",y+'a'-x-1,i++);
}
}
本文介绍了一个简单的字符到数值转换程序,该程序通过给定字母和一个整数来计算特定的数学结果。输入包括一系列测试案例,每个案例由一个字母和一个整数组成,输出则是整数与字母对应数值相加的结果。
