Do a binary search.
find the mid element.
Check for break point.
Return the index.
Driver code.
print the smallest number"

#Here is code to minimum in an array which is first decreasing then increasing and the other steps required.
 def minimal ( a , n ) :
	lo , hi = 0 , n - 1
	while lo < hi :
		mid = ( lo + hi ) // 2
		if a [ mid ] < a [ mid + 1 ] :
			hi = mid
		else :
			lo = mid + 1
		return lo
		return lo
a = [ 8 , 5 , 4 , 3 , 4 , 10 ]
n = len ( a )
ind = minimal ( a , n )
print ( a [ ind ] )
