In this question here we have to write a code, python code for the regression function.
00:07
Here we have def row underscore puzzle underscore rec bracket row comma pause comma visited.
00:24
So next we have to apply if condition in which if the row pause is equal equal to zero then here the possible is equal to true.
00:41
Here else the visited is equal to visited square bracket.
00:53
Here again we are applying the if condition in which if the visited is bracket pause here the possible is equal to false.
01:09
Here else the visited pause is equal to true then the possible is equal to false.
01:27
Here again we have to apply the if it's possible to move left from the recursion in the left direction.
01:36
So here we have the if pause row here pause is greater than zero and the row underscore puzzle underscore rec bracket row comma pause row pause comma visited.
02:05
So here return immediately so here return true.
02:13
Here now again we have to apply the if pause plus row pause is smaller than len row and the row underscore puzzle underscore rec row pause plus row pause comma visited bracket close...
