There are three houses on a number line: House 1, 2 and 3, with coordinates A, B and C, respectively. Print `Yes` if we pass the coordinate of House 3 on the straight way from House 1 to House 2 without making a detour, and print `No` otherwise.
a,b,c=map(int,input().split())
if a<c and c>b:
  print('Yes')
else:
  print('No')
a,b,c=map(int,input().split())
if a<c and b>c:
  print('Yes')
elif b<c and a>c:
  print('Yes')
else:
  print('No')
