Give me a code to maximum length of subarray with same sum at corresponding indices from two Arrays and the other steps required given the following:
Maximum length of subarray with same sum at corresponding indices from two Arrays | Function to find maximum length of subarray of array A and B having equal sum.
Stores the maximum size of valid subarray.
Stores the prefix sum of the difference of the given arrays.
Traverse the given array.
Add the difference of the corresponding array element.
If current difference is not present.
If current difference is present , update the value of maxSize.
Return the maximum length.
Driver Code"
How can the above be solved in Python?

			pre = i + 1
		else :
			maxSize = max ( maxSize , i - pre + 1 )
	return maxSize
if __name__ == " _ _ main _ _ " :
	A = [ 1 , 2 , 3 , 4 ]
	B = [ 4 , 3 , 2 , 1 ]
	print ( maxLength ( A , B ) )
