Le lettere delle parole vogliono equità.

Hanno deciso di apparire allo stesso numero di volte in una frase allo stesso modo.

Esempio:

Priorities

Diventerà:

Ppprrioooritttieeesss

Ogni lettera appare 3 volte, come era la lettera più comune i, appare 3 volte.

Non importa dove metti le lettere ripetute, purché siano accanto a una lettera simile.

Vale a dire:

Pppriooorritttieeesss è OK (la lettera 'r')

Ppprioororitttieeesss non va bene (la lettera 'r')

Un altro esempio:

invoice

Diventerà:

innvvooiccee

Un altro esempio:

Remittance Advice

Diventerà:

Rrremmmiitttaannncce Adddvvvice

Spazio, virgola, punto interrogativo, citazione, ecc. Non sono considerati lettere per questa sfida. Devo solo considerare [a-zA-Z]. Solo una volta lo spazio è sufficiente e l'ordine delle lettere dovrebbe rimanere lo stesso.

La maiuscola delle lettere non ha importanza, le lettere maiuscole e minuscole sono conteggiate come la stessa lettera. Cioè: Pipha 2 'P e 1' I ', quindi diventerà Piip.

È possibile che le lettere senza distinzione tra maiuscole e minuscole possano essere in qualsiasi forma, Piip=piip=piiP=PiiP

Questo è code-golf
