程式碼:

import java.util.Arrays;
import java.util.Scanner;
public class d984 {

 public static void main(String[] args) {
  // TODO Auto-generated method stub
  Scanner sc = new Scanner(System.in);
  while(sc.hasNext()){
   long a = sc.nextLong();//候選人a
   long b = sc.nextLong();//候選人b
   long c = sc.nextLong();//候選人c
   long [] arr = new long[3];//儲存陣列
   arr [0] = a;
   arr [1] = b;
   arr [2] = c;
   Arrays.sort(arr);//排序
   long unknow = (arr[0]+arr[1] > arr[2])? arr[1]:arr[2];//把比較結果傳入
   if(unknow == a) {
                System.out.println("A");                
            } else if(unknow == b) {
                System.out.println("B");
            } else {                
                System.out.println("C");
            }
   //int 不行會有益位
  }
