Serbare1
Anul acesta la serbarea de Crăciun, doamna învățătoare de la clasa întâi a hotărât să aranjeze elevii pe mai multe rânduri, după înălțime. Pe primul rând (cel din spatele scenei) va aranja în ordinea lexicografică a numelor, elevii care au înălțimea maximă, apoi în fața lor, tot în ordinea lexicografică a numelor elevii care au următoarea înălțime, ș.a.m.d. Fiind cam de aceeași vârstă, mulți dintre elevi au înălțimi egale.
Scrieţi un program care să citească numărul natural N
(reprezentând numărul de elevi), apoi în ordine de pe linii diferite numele și înălțimea fiecărui elev și care să determine:
a) Numărul de rânduri pe care vor fi așezați elevii
b) Numărul de elevi de pe fiecare rând, urmat de elevii de pe rândul respectiv în ordinea lexicografică a numelor.
