I assume: DC doesn't count as a state.
Spaces in state names ("Rhode Island") are left out ("RhodeIsland") with no effect on the result. RhodeIsland has 11 letters, not 12. Case is unimportant. Every uppercase "A" matches a lowercase "a" in the results. Every letter is reused once. No letter is left out. No letter is used twice. I'm just doing some noodling about the problem -- I think a lot of eliminations can be made on some basics I discovered: The shortest state names have 4 letters; the longest, 13. Therefore, numbers between 4 and 13 have to be partitioned into pairs, and any pair with an integer less than 4 can be eliminated right off the bat. After doing this, I have left only 4+9=13 5+8=13 6+7=13 4: Iowa Ohio Utah 5: Idaho Maine Texas 6: Alaska Hawaii Kansas Nevada Oregon 7: Alabama Florida Georgia Indiana Montana NewYork Vermont Wyoming (Arizona too, but it has already been eliminated, remember?) 8: Arkansas Colorado Delaware Illinois Kentucky Maryland Michigan Missouri Nebraska Oklahoma Virginia 9: Louisiana Minnesota NewJersey NewMexico Tennessee Wisconsin So this narrows the choice somewhat: Does Iowa + Minnesota = Georgia + Nevada? Well, no, but we can work the remaining possibilities exhaustively. But that takes care only of the 13-letter possibilities! Still have to look at 4-12. Other eliminations can be based on letter occurrences. For instance, New Jersey is the only state with a "j", and Arizona is the only one with a "z". So neither one can appear in the result.
