Problem Statement

In AtCoder city, there are five antennas standing in a straight line. They are called Antenna $A, B, C, D$ and $E$ from west to east, and their coordinates are $a, b, c, d$ and $e$, respectively. Two antennas can communicate directly if the distance between them is $k$ or less, and they cannot if the distance is greater than $k$. Determine if there exists a pair of antennas that cannot communicate directly. Here, assume that the distance between two antennas at coordinates $p$ and $q$ ($p < q$) is $q - p$.

Constraints

• $a, b, c, d, e$ and $k$ are integers between $0$ and $123$ (inclusive).
• $a < b < c < d < e$

Input

Input is given from Standard Input in the following format:

a
b
c
d
e
k

Output

Print :( if there exists a pair of antennas that cannot communicate directly, and print Yay! if there is no such pair.
