Three people, A, B and C, are trying to communicate using transceivers. They are standing along a number line, and the coordinates of A, B and C are a, b and c (in meters), respectively. Two people can directly communicate when the distance between them is at most d meters. Determine if A and C can communicate, either directly or indirectly. Here, A and C can indirectly communicate when A and B can directly communicate and also B and C can directly communicate.
a, b, c, d = map(int, input().split())

if max(b-a,c-d) > d:
    print("No")
else:
    print("Yes")
a,b,c,d = map(int, input().split())
 
if (abs(b-a) <= d and abs(c-b) <= d) or abs(c-a) <= d:
    print("Yes")
else:
    print("No")
