Problem Description There must be many A + B problems in our HDOJ , now a new one is coming.
Give you two hexadecimal integers , your task is to calculate the sum of them,and print it in hexadecimal too.
Easy ? AC it !
Input The input contains several test cases, please process to the end of the file.
Each case consists of two hexadecimal integers A and B in a line seperated by a blank.
The length of A and B is less than 15.
Output For each test case,print the sum of A and B in hexadecimal in one line.
Sample Input +A -A +1A 12 1A -9 -1A -12 1A -AA
Sample Output 0 2C 11 -2C -90
Author linle 涉及到进制格式问题：X 表示大写的16进制，x表示小写的16进制； 代码
#include<stdio.h>
int main()
{
_int64 a,b;
while(scanf("%I64X%I64X",&a,&b)==2)
{
if(a+b<0)
printf("-%I64X\n",-(a+b));
else
printf("%I64X\n",a+b);
}
return 0;
}编程是一种快乐，享受代码带给我的乐趣！！！
