I have partitioned the list of US states into two groups based on a certain property that is shared by 32 states but not shared by the remaining 18 states.
The 32 states that share this property:
?????, ?????, California, Georgia, Hawaii, Idaho, Indiana, Louisiana, Maryland, Massachusetts, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wyoming.
The 18 states that do not have the property:
?????, ?????, Colorado, Connecticut, Delaware, Florida, Illinois, Iowa, Kansas, Kentucky, Maine, Michigan, Minnesota, Mississippi, Missouri, Ohio, Tennessee, Wisconsin.
What property did I use for my partition?
To which parts do Alabama, Alaska, Arizona and Arkansas belong?
