#Here is code to check if a binary string contains all permutations of length k and the other steps required.
 def hasAllcodes ( s , k ) :
	us = set ( )
	for i in range ( len ( s ) + 1 ) :
		us . add ( s [ i : k ] )
	return len ( us ) == 1 << k
s = "00110110"
k = 2
if ( hasAllcodes ) :
	print ( " YES " )
else :
	print ( " NO " )
