CString을 cout 으로 출력할 때는 캐스팅이 필요하다.


cout  << (LPCSTR)(LPCTSTR) CSTring ;

cout  << CString;   ← 이렇게 하면 주소값이 스트링 형태로 출력된다.


역시 확실히 알아두지 않으면 곤란해..
멀쩡하게 잘 돌아가는 프로그램을 요고 때문에 계속 헷갈려하고 ㅋ

George took sticks of the same length and cut them randomly until all parts became at most 50 units long. Now he wants to return sticks to the original state, but he forgot how many sticks he had originally and how long they were originally. Please help him and design a program which computes the smallest possible original length of those sticks. All lengths expressed in units are integers greater than zero.

Input

The input file contains blocks of 2 lines. The first line contains the number of sticks parts after cutting. The second line contains the lengths of those parts separated by the space. The last line of the file contains zero.

Output

The output file contains the smallest possible length of original sticks, one per line.
