Unendlich wird als Kleinbuchstabe ( 'abcdefghijklmnopqrstuvwxyz'
) eingegeben .
Probieren Sie es online aus oder überprüfen Sie alle Testfälle .
Wichtiger Hinweis: Wenn es ein tatsächliches Infinity
und gegeben hätte -Infinity
, wären es stattdessen 43 bis 42 Bytes gewesen . So etwas über 50% um 30% ist als Abhilfe für den Mangel an Infinity
..

Probieren Sie es online aus (mit Infinity
ersetzt durch 9999999999
und -Infinity
ersetzt durch -9999999999
).
Kann definitiv erheblich golfen werden. Am Ende war es sehr, sehr hässlich und voller Workarounds. Aber jetzt bin ich nur froh, dass es funktioniert.
