#857

Gigel învaţă la matematică despre mulţimi. A scris pe foaie o mulţime formată din litere mari şi mici ale alfabetului englez, considerate identice. A separat elementele cu virgule (,) şi a delimitat mulţimea cu acolade. Din păcate, în mulţimea scrisă de Gigel se pot repeta litere, sau pot să apară şi litera mare şi litera mică. Gigel vă roagă să-l ajutaţi să corecteze acea mulţime, adică:

• să eliminaţi dublurile;
• să ordonaţi alfabetic elementele;
• dacă cel puţin jumătate dintre elementele iniţiale sunt litere mari, să transformaţi toate elementele în litere mari; în caz contrar să transformaţi toate elementele în litere mici.
