Can you provide a code to minimum inversions required so that no two adjacent elements are same and the other steps required given the following:
Minimum inversions required so that no two adjacent elements are same | Function to return the minimum inversions required so that no two adjacent elements are same.
To store the inversions required to make the array { 1 , 0 , 1 , 0 , 1 , 0 , 1 , ... } and { 0 , 1 , 0 , 1 , 0 , 1 , 0 , ... } respectively.
Find all the changes required.
Return the required answer.

#Here is code to minimum inversions required so that no two adjacent elements are same and the other steps required.
 def min_changes ( a , n ) :
	ans_a = 0 ;
	ans_b = 0 ;
	for i in range ( n ) :
		if ( i % 2 == 0 ) :
			if ( a [ i ] == 0 ) :
				ans_a += 1 ;
			else :
				ans_b += 1 ;
		else :
			if ( a [ i ] == 0 ) :
				ans_b += 1 ;
			else :
				ans_a += 1 ;
	return min ( ans_a , ans_b ) ;
if __name__ == ' _ _ main _ _ ' :
	a = [ 1 , 0 , 0 , 1 , 0 , 0 , 1 , 0 ] ;
	n = len ( a ) ;
	print ( min_changes ( a , n ) ) ;
