Challenge : zitf
Enoncé :
As a huge fan of ZITF, you want to display "ZITF" on a 14-segment display. A diagram of the 14 segments layout show how segments should be powered on.
The output should be in the format ZiTF{<bits of letter 1><bits of letter 2>...}.
For example, "ABC" becomes ZiTF{000000111101110000111000111100000000111001}.
Segments A is at position 2^13 and segment N at 2^0.
Ressource :
Mapping des segments → bits :
A → bit 0 B → bit 1 C → bit 2 D → bit 3 E → bit 4 F → bit 5 G → bit 6 H → bit 7 I → bit 8 J → bit 9 K → bit 10 L → bit 11 M → bit 12 N → bit 13
Affichage des lettres par segment :
Z utilise les segments :
A (bit 0)
L (bit 11)
M (bit 12)
D (bit 3)
I utilise les segments :
I (bit 8)
J (bit 9)
A (bit 0)
D (bit 3)
T utilise les segments :
A (bit 0)
I (bit 8)
J (bit 9)
F utilise les segments :
A (bit 0)
F (bit 5)
E (bit 4)
G (bit 6)
