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
import java.util.*;class Main{ public static void main(String _[]) { Scanner sc=new Scanner(System.in); while(sc.hasNext()){ String a=sc.next(); String b=sc.next(); long i=Long.parseLong(a.replaceAll("//+",""),16)+Long.parseLong(b.replaceAll("//+",""),16); if(i<0)System.out.println("-"+Long.toHexString(-i).toUpperCase()); else System.out.println(Long.toHexString(i).toUpperCase()); } }}新闻热点
