题面：
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).
\(a<b<c<d<e\)
