题目
解题思路
这就是个计算题,A ,B, C三人的糖果我们都不知道,但根据他给的示例可以得出这样的结果:
1: (A - B) +(A + B) = 2A;
2: (B + C) - (B - C) = 2C;
3: (B - C) + (B + C) = 2B;
4: (A + B) - (A - B) = 2B;
3 和 4就可以判断出是否存在这样的整数了
解题代码
import java.util.*;
public class Main{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
int a = scan.nextInt();
int b = scan.nextInt();
int c = scan.nextInt();
int d = scan.nextInt();
int A = (a + c) / 2;
int C = (d - b) / 2;
int B1 = (b + d) / 2;
int B2 = (c - a) / 2;
if(B1 != B2){
System.out.println("No");
}else{
System.out.println(A+" "+B1+" "+C);
}
}
