Solution in Python:
assistant
#Here is code to block swap algorithm for array rotation and the other steps required.
 def leftRotate ( arr , d , n ) :
	if ( d == 0 or d == n ) :
		return ;
	i = d
	j = n - d
	while ( i != j ) :
		if ( i < j ) :
			swap ( arr , d - i , d + j - i , i )
			j -= i
		else :
			swap ( arr , d - i , d , j )
			i -= j
	swap ( arr , d - i , d , i )
