A string is called a KEYENCE string when it can be changed to `keyence` by removing its contiguous substring (possibly empty) only once.  Given a string S consisting of lowercase English letters, determine if S is a KEYENCE string.
s = str(input())
n = len(s)
if s == "keyence":
 print("YES")
 exit()
else:
 for I in range(8):
  t = s[0:I]+s[I+n-7:n]
  print(t)
  if t == "keyence":
   print("YES")
   exit()
print("NO")
s = str(input())
n = len(s)
if s == "keyence":
 print("YES")
 exit()
else:
 for I in range(8):
  t = s[0:I]+s[I+n-7:n]
  if t == "keyence":
   print("YES")
   exit()
print("NO")
