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

            int y = int.Parse(s[3]);
            int r = int.Parse(s[4]);

            if (w > 0) //w>0?????¨???
            {
                if((w < (x+r)) || (0 > (x-r)))
