#4973

Natașa este o pisică foarte vorbăreață: ea poate pronunța toate vocalele (a, e, i, o, u) și consoana m. Am observat că mesajul pe care Natașa încearcă să mi-l transmită este o secvență dintr-o “frază” scrisă în limbaj pisicesc, care are un număr maxim de apariţii în frază. Dacă există mai multe secvențe cu număr maxim de apariții, mesajul este secvența cu lungimea cea mai mare. Scrieți un program care citește un șir de caractere, ce reprezintă o frază în limbaj pisicesc și rezolvă următoarele cerințe:
1. determină numărul de vocale distincte existente în frază;
2. determină de câte ori apare secvența mau în frază;
3. determină mesajul transmis de Natașa, conform regulilor de mai sus.
