最佳解

1.程式碼

import java.util.Scanner;

class Java2015 {
 public static void main(String args[]) throws Exception {
  int x = 0, y = 0, z = 0;

  Scanner scanner = new Scanner(System.in);
 Scanner a = new Scanner(System.in);
Scanner b = new Scanner(System.in);
Scanner c = new Scanner(System.in);
Scanner d = new Scanner(System.in);
Scanner e = new Scanner(System.in);
Scanner f = new Scanner(System.in);

  System.out.println("請輸入最大值Z:");

z = scanner.nextInt();

System.out.println("請輸入方程式二元一次係數:");

int A = a.nextInt();

int B = b.nextInt();

int C = c.nextInt();

int D = d.nextInt();

int E = e.nextInt();

int F = f.nextInt();



 while (y < z) {
   y = A*x*x*x*x*x + B*x*x*x*x + C*x*x*x+D*x*x+E*x+F;
   x++;
  }
  x=(x-2);
  System.out.print("當x為:" + x);
  System.out.print(" y:" + (A*x*x*x*x*x + B*x*x*x*x + C*x*x*x+D*x*x+E*x+F));
  System.out.println(",符合y<Z");

 }
}

2.第一行輸入最大值
   第二行輸入二元一次方程式的係數(共6個)
如果覺得五次方太多可在係數前打0，看個人需要幾次方方程式
