Circle in a Rectangle

Write a program which reads a rectangle and a circle, and determines whether the circle is arranged inside the rectangle. As shown in the following figures, the upper right coordinate $(W, H)$ of the rectangle and the central coordinate $(x, y)$ and radius $r$ of the circle are given.

Input

Five integers $W$, $H$, $x$, $y$ and $r$ separated by a single space are given in a line.

Output

Print "Yes" if the circle is placed inside the rectangle, otherwise "No" in a line.

Constraints

$ -100 \leq x, y \leq 100$

$ 0 < W, H, r \leq 100$

Sample Input 1

5 4 2 2 1

Sample Output 1

Yes

Sample Input 2

5 4 2 4 1

Sample Output 2

No

Solution in C# (judge verdict: Wrong Answer)

using System;

class MyClass
{
    public static void Main()
    {
        string[] str = Console.ReadLine().Split(' ');
        int[] array = new int[str.Length];
        for (int i = 0; i < str.Length; i++)
            array[i] = int.Parse(str[i]);
        //[0]:W, [1]:H, [2]:x, [3]:y, [4]:r
        int W = array[0];
        int H = array[1];
        int x = array[2];
        int y = array[3];
        int r = array[4];

        if (Math.Sign(W) == 1 && x + r > W)
            Console.WriteLine("No");
        else if (Math.Sign(W) == -1 && x - r < W)
            Console.WriteLine("No");
        else if (Math.Sign(H) == 1 && y + r > H)
            Console.WriteLine("No");
        else if (Math.Sign(H) == -1 && y - r < H)
            Console.WriteLine("No");
        else
            Console.WriteLine("Yes");
    }
