#Here is code to queries to answer the number of ones and zero to the left of given index and the other steps required.
 def preCalculate ( binary , n , left ) :
	count1 , count0 = 0 , 0
	for i in range ( n ) :
		left [ i ] [ 0 ] = count1
		left [ i ] [ 1 ] = count0
		if ( binary [ i ] ) :
			count1 += 1
		else :
			count0 += 1
binary = [ 1 , 1 , 1 , 0 , 0 , 1 , 0 , 1 , 1 ]
n = len ( binary )
left = [ [ 0 for i in range ( 2 ) ] for i in range ( n ) ]
preCalculate ( binary , n , left )
queries = [ 0 , 1 , 2 , 4 ]
q = len ( queries )
for i in range ( q ) :
	print ( left [ queries [ i ] ] [ 0 ] , " ones " , left [ queries [ i ] ] [ 1 ] , " zeros " )
