Zarywam kolejne 2 znaki - razem udalo mi sie "wydrzec" 8 :)
for(s=b='',a=5;N;b++,a=7-a)
for(o=N%a,N=N/a^0;o;)
s='IVXLCDM'.charAt(o-->3?b+N%2+(N&=~1,o=1):b)+s
Troche poprzestawialem kod, ale to akurat nie jest istotne,
natomiast zwroc uwage na s=b=''
Za jednym zamachem deklaruje pustego stringa, oraz inicjuje b jako 0
- co prawda to, ze b jest zerem, wychodzi dopiero przy inkrementacji:
var b
alert(b++) // kicha
b=''
alert(b++) // 1 - i o to chodzi
Vax, say You are proud of me... ;-)
