Through a little deduction, you should now be able to determine the remaining digits. Consider again the first example above:
|
|
|
|
acedgfb cdfbe gcdfa fbcad dab cefabd cdfgeb eafb cagedb ab |
|
|
cdfeb fcadb cdfeb cdbaf
|
|
After some careful analysis, the mapping between signal wires and segments only make sense in the following configuration:
|
|
|
|
dddd
|
|
e a
|
|
e a
|
|
ffff
|
|
g b
|
|
g b
|
|
cccc
|
|
So, the unique signal patterns would correspond to the following digits:
|
|
|
|
acedgfb: 8
|
|
cdfbe: 5
|
|
gcdfa: 2
|
|
fbcad: 3
|
|
dab: 7
|
|
cefabd: 9
|
|
cdfgeb: 6
|
|
eafb: 4
|
|
cagedb: 0
|
|
ab: 1
|
|
Then, the four digits of the output value can be decoded:
|
|
|
|
cdfeb: 5
|
|
fcadb: 3
|
|
cdfeb: 5
|
|
cdbaf: 3
|
|
Therefore, the output value for this entry is 5353.
|
|
|
|
Following this same process for each entry in the second, larger example above, the output value of each entry can be determined:
|
|
|
|
fdgacbe cefdb cefbgd gcbe: 8394
|
|
fcgedb cgb dgebacf gc: 9781
|
|
cg cg fdcagb cbg: 1197
|
|
efabcd cedba gadfec cb: 9361
|
|
gecf egdcabf bgf bfgea: 4873
|
|
gebdcfa ecba ca fadegcb: 8418
|
|
cefg dcbef fcge gbcadfe: 4548
|
|
ed bcgafe cdgba cbgef: 1625
|
|
gbdfcae bgc cg cgb: 8717
|
|
fgae cfgab fg bagce: 4315
|
|
Adding all of the output values in this larger example produces 61229.
|
|
|
|
For each entry, determine all of the wire/segment connections and decode the four-digit output values. What do you get if you add up all of the output values? |
