Jeg tjekkede ikke sandkassen før jeg sendte denne udfordring – det ser ud til, at denne udfordring blev foreslået af Cᴏɴᴏʀ O “Bʀɪᴇɴ .
Givet et heltal input, skriv et program, der udskriver de” fire er et magisk tal “gåde
- Fire er det magiske tal
- Fem er fire og fire er det magiske tal
- Seks er tre og tre er fem og fem er fire og fire er det magiske tal
- Elleve er seks og seks er tre og tre er fem og fem er fire og fire er det magiske tal
- Fem hundrede er elleve og elleve er seks og seks er tre og tre er fem og fem er fire og fire er det magiske nummer
Hvis du allerede kender gåden, eller er for doven til at løse det ivrig efter at finde ud af, hvad gåden er, her er en forklaring
Det næste tal er antallet af bogstaver i det forrige nummer. Så for e eksempel, fem har fire bogstaver, så det næste tal er fire .
seks har tre bogstaver, så det næste tal er 3 , og tre har fem bogstaver, så det næste tal er 5 , og fem har fire bogstaver, så det næste tal er 4
Grunden til, at gåden ender med fire, er fordi fire har fire bogstaver, og fire er fire og fire er fire og fire er fire … (fire er det magiske tal )
Testtilfælde

Regler
- Indgangen kan enten tages fra
STDIN
eller som et argument til en funk tion - Input vil være et positivt tal mellem 0 og 999.999
- Input vil kun indeholde tal (det følger regex
^[0-9]+$
) - Input kan enten tages som et heltal eller en streng
- Når det konverteres til en ordstreng, skal mellemrum og bindestreger ikke medtages i optælling (100 [Hundrede] er 10 tegn, ikke 11. 1.742 [Tusind syvhundrede fyrre-to] er 31 tegn, ikke 36)
- Når det konverteres til en streng, skal 100 være hundrede, ikke hundrede eller hundrede, 1000 skal være tusind, ikke tusind eller tusind.
- Når det konverteres til en streng 142, skal det være et hundrede og fyrre, ikke et hundrede og fyrre To
- Outputtet er store og små bogstaver og skal følge formatet “ N er K og K er M og M er … og fire er det magiske tal “(medmindre input er 4, i hvilket tilfælde output skal være” fire er det magiske tal “)
- Outputtet kan bruge tal i stedet for bogstaver (“5 er 4 og 4 er det magiske tal” i stedet for “fem er fire og fire er det magiske tal”), så længe dit program altid er ensartet
- Outputtet kan enten være returværdien af en funktion eller udskrives til
STDOUT
- Standard smuthuller gælder
- Dette er code-golf , så det korteste program i bytes vinder. Held og lykke!
Bonus
-30 bytes hvis programmet fungerer, når input er mellem -999.999 og 999.999.
Negative tal, når de konverteres til ord, skal du bare have “negativ” foran dem. For eksempel er -4
“Negativ Fire”, Negativ Fire er tolv og tolv er seks og seks er tre og tre er fem og fem er fire og fire er det magiske tal
-150 bytes hvis programmet ikke bruger nogen indbyggede funktioner til generering strengrepræsentationen af nummeret
Leaderboard
Dette er et stakuddrag, der genererer både et leaderboard og en oversigt over vindere efter sprog.

Hvor N er størrelsen , i byte, af din indsendelse
Hvis du vil medtage flere tal i dit overskrift (f.eks. at slå gennem gamle scores eller inkludere flag i byte-antallet), skal du bare sørge for at den faktiske score er sidste nummer i din overskrift

en anden havde din idé .

Inspireret af svaret fra Cole Cameron . Jeg tænkte, at jeg muligvis kunne klare mig bedre uden makrodefinitionen. Selvom det til sidst lykkedes mig, krævede det noget pres for at opnå det!
Det kræver et værtssæt med på hinanden følgende bogstaver (så ASCII er okay, men EBCDIC fungerer ikke). Det er for parret opslagstabeller. Jeg valgte j
som nultegn og udnyttede behovet for to opslag, så jeg kunne trække den ene fra den anden i stedet for at skulle trække mit nul fra begge.
Kommenteret version:
char*i= "jmmonnmoon" /* 0 to 9 */ "mpprrqqsrr" /* 10 to 19 */ "jjddeeecdd"; /* tens */ char x; /* current letter count */ f(n,c){ return !n?n /* zero - return 0 (ignore c) */ :n<0?f(-n,8) /* negative n (only reached if c==0) */ :n<100?c+i[n<20?n:n%10]-i[20+n/10] /* lookup tables */ : f(n/1000,8) /* thousand */ + f(n/100%10,7) /* hundred */ + f(n%100,0) /* rest */ + c; /* carry-in */ } main(int c, char**v) { for(c=atoi(*++v);c-4;c=x) printf("%d is %d and ",c,x=c?f(c,0):4); puts("4 is the magic number"); }
Der er en åbenbar udvidelse til at støtte millioner ved at erstatte f(n/1000,8)
med f(n/1000000,7)+f(n/1000%1000,8)
.

Python 641-150 = 501 byte
Det er i det mindste ikke længere end Java! Det er baseret på dette undtagen ved hjælp af strenge.
EDIT : I glemte 0 og at jeg har brug for at sige " 5 er 4 ", ikke spring til " 4 er det magiske tal " – der tilføjede lidt til partituret.

Moo, 182 176 / 192 188 bytes – 30 = 146/158
188 byte-version:

176 byte implementeringsafhængig version:

Begge er funktioner.

Og jeg troede JS ' sString.fromCharCode
var detaljeret. : Pstring.replace
