Les lettres des mots veulent l'équité.

Ils ont décidé d'apparaître de manière égale le même nombre de fois dans une phrase.

Exemple:

Priorities

Va devenir:

Ppprrioooritttieeesss

Chaque lettre apparaît 3 fois, comme la lettre la plus courante i, apparaissant 3 fois.

Peu importe où vous mettez les lettres répétées, tant qu'elles sont à côté d'une lettre similaire.

C'est à dire:

Pppriooorritttieeesss est OK (la lettre «r»)

Ppprioororitttieeesss n'est pas OK (la lettre «r»)

Un autre exemple:

invoice

Va devenir:

innvvooiccee

Un autre exemple:

Remittance Advice

Va devenir:

Rrremmmiitttaannncce Adddvvvice

L'espace, la virgule, le point d'interrogation, la citation, etc. ne sont pas considérés comme des lettres pour ce défi. Il suffit de considérer [a-zA-Z]. Une fois que l'espace est suffisant, l'ordre des lettres doit rester le même.

La majuscule des lettres n'a pas d'importance, les majuscules et les minuscules sont des comptés comme la même lettre. C'est-à-dire: Pipa 2 «P» et 1 «I», il deviendra donc Piip.

Il est possible que les lettres insensibles à la casse se présentent sous n'importe quelle forme, Piip=piip=piiP=PiiP

  new.l = strrep(l,m-s[letters==l]+1)
    # Substitute the first instance only of the letter in the string for the repeated letter
    # This is case insensitive (the T at the end)
