There is a street with 9 houses in a row, numbered from 1 to 9:
1 2 3 4 5 6 7 8 9
There is a burglar on the street. He always steals one of the 9 houses
each night. He is disciplined such that if he steals a house one night,
then the next night he will steal a house that is adjacent. In maths, if
he steals house i one night, then the next night he will steal either
