Esta ideia é vagamente baseada na mensagem de bate-papo de @ TùxCräftîñg .
Dê uma olhada na sequência de exemplo abaixo:
INVALID0
, INVALID1
, INVALID2
INVALID3
, INVALID4
...INVALID9
Depois INVALID9
, continua assim:
INVALI0
, INVALI1
, INVALI2
, INVALI3
...INVALI9
E depois INVALI9
, é assim:
INVAL0
, INVAL1
, INVAL2
, INVAL3
...INVAL9
Depois, INVAL9
é assim:
INVA0
, INVA1
, INVA2
, INVA3
, ...INVA9
Observe como sempre removíamos uma letra da palavra INVALID
.
Você continuará repetindo isso até chegar a uma única letra, ou seja, a letra I
:
I0
, I1
, I2
, I3
, I4
...I9
Agora, sua tarefa é pegar uma entrada de uma palavra e produzir uma sequência a partir dela, como no exemplo acima. Seu código também deve funcionar com letras únicas e, nesse caso, a sequência resultante será mais curta.
Você pode escolher qualquer formato de entrada e saída que preferir (com ou sem um separador, conforme desejar), mas deve especificar qual você escolheu.
A sequência precisa estar na ordem exata especificada.
O código mais curto, em bytes, que conclui esse desafio com êxito, vence o desafio.
Sequência completa no exemplo acima:
INVALID0, INVALID1, INVALID2, INVALID3, INVALID4, INVALID5, INVALID6, INVALID7, INVALID8, INVALID9, INVALI0, INVALI1, INVALI2, INVALI3, INVALI4, INVALI5, INVALI6, INVALI7, INVALI8, INVALI9, INVAL0, INVAL1, INVAL2, INVAL3, INVAL4, INVAL5, INVAL6, INVAL7, INVAL8, INVAL9, INVA0, INVA1, INVA2, INVA3, INVA4, INVA5, INVA6, INVA7, INVA8, INVA9, INV0, INV1, INV2, INV3, INV4, INV5, INV6, INV7, INV8, INV9, IN0, IN1, IN2, IN3, IN4, IN5, IN6, IN7, IN8, IN9, I0, I1, I2, I3, I4, I5, I6, I7, I8, I9
