#Here is code to maximum size of sub and the other steps required.
 def cmp ( a , b ) :
	return ( a > b ) - ( a < b )
def maxSubarraySize ( arr ) :
	N = len ( arr )
	ans = 1
	anchor = 0
	for i in range ( 1 , N ) :
		c = cmp ( arr [ i - 1 ] , arr [ i ] )
		if c == 0 :
			anchor = i
		elif i == N - 1 or c * cmp ( arr [ i ] , arr [ i + 1 ] ) != - 1 :
			ans = max ( ans , i - anchor + 1 )
			anchor = i
	return ans
arr = [ 9 , 4 , 2 , 10 , 7 , 8 , 8 , 1 , 9 ]
print ( maxSubarraySize ( arr ) )
