Question

我有一个二维整数数组和一个二维双数组。如果double数组中的值小于二维数组的相同位置处的整数值，则在布尔数组的该部分中，值将为true。如果它更大，那么布尔值将是false。

我将如何解决这个问题？

这是我到目前为止所尝试的：

public static boolean[][] CompareIntDouble(int[][] pizza, double[][] pasta) {
    boolean x = true;

    for (int hotdog=0; hotdog < pizza.length; hotdog++) {
        for (int toast=0; toast < pizza[hotdog].length; toast++) {
            pizza[hotdog][toast] = hotdog * 10 + toast;

            if (pasta[1][1] > pizza[1][1]) {
                x = true;
            } else {
                x = false;
            }

            if (pasta[1][2] > pizza[1][2]) {
                x = true;
            } else {
                x = false
            }
        }
    }
}

Picture of the code

Answer 1

public static void main(String... args) throws IOException {
    int[][] t1 = new int[2][2];
    t1[0][0] = 0;
    t1[0][1] = 1;
    t1[1][0] = 2;
    t1[1][1] = 3;

    double[][] t2 = new double[2][2];
    t2[0][0] = 3;
    t2[0][1] = 2;
    t2[1][0] = 1;
    t2[1][1] = 0;

    boolean[][] f = new boolean[2][2];

    for (int i = 0; i < 2; i++) {
        for (int j = 0; j < 2; j++) {
            if (t1[i][j] > t2[i][j]) {
                f[i][j] = true;
            } else {
                f[i][j] = false;
            }
            System.out.println(i+" "+j+" :"+f[i][j]);
        }
    }
}

即使你应该先自己尝试一下这里有一个有效的例子

假设2d输入数组具有相同的大小

use App\user;
use Illuminate\Foundation\Auth\SendsPasswordResetEmails;

class guestController extends Controller
{

    public function __construct()   {        $this->middleware('guest');    }

    use SendsPasswordResetEmails;

    public function sendPasswordEmail(request $request)
    {
        $a=user::where('email',Request('email'))->first();
        if(count($a)>0){
            $this->sendResetLinkEmail($request);
            return redirect('password/emailThankyou');
        } else {
            return redirect()->back();
        }
    }

从另外两个数组创建二维布尔数组
