內容

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.

輸入說明

The input contains several test cases. Each test case has two 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 0 indicating the end of input.

all the numbers in input are all less equal than 50

輸出說明

Output the smallest possible length of original sticks, one test case per line.
