No Challenge text but a picture of the beautiful Eiffel Tower with some unusual color lights on it.
We know the Binary system, used in computers, is made of 1’s and 0’s.
There is another system, the ternary system using 0, 1 and 2.
We can count as this : 1, 2, 10, 11, 12, 20, 21, 22, 100, 101, 102… (counting from decimal 1 to 11) which you can see resembles binary except you have an additional digit of 2.
Using that system, here is a link to help : http://www.mathsisfun.com/numbers/convert-base.php?to=ternary, we can find the decimal values of this code.
200 18
012 5
021 7
112 14
001 1
200 18
200 18
012 5
212 23
120 15
121 16
And then finding the letters : 1 is A, 2 is B, … 26 is Z
200 18 R
012 5 E
021 7 G
112 14 N
001 1 A
200 18 R
200 18 R
012 5 E
212 23 W
120 15 O
121 16 P
