#4854
Scrieți un program care citește de la tastatură două numere naturale din intervalul [2,100], m și n, și elementele unui tablou bidimensional cu m linii și n coloane, numere naturale distincte din intervalul [0,109].
Programul modifică tabloul în memorie, înlocuind valorile tuturor elementelor aflate pe coloana care conține numărul minim memorat în tablou cu valoarea elementului aflat pe ultima linie și ultima coloană. Tabloul obținut este afișat pe ecran, câte o linie a tabloului pe câte o linie a ecranului, elementele fiecărei linii fiind separate prin câte un spațiu.
