Problem Description A number of students sit in A circle facing their teacher in the center. Each student initially have an even number of pieces of candy. When the teacher blows a whistle, each student simultaneously gives half of he or her candy to the neighbor on the right. Any student, who ends-a odd number of pieces of candy, is given another piece by the teacher. The game ends when all students has the same number of pieces of candy.
Write a program which determines the number of times the the teacher blows the whistle and the final number of pieces of candy For each student from the amount of candy each child starts with.

Input the input may describe more than one game. For each game, the input begins with the number N of students, followed by N (even) candy counts for the children counter- Clockwise around the circle. The input ends with a student count of 0. Each of the input number is on a line by itself.

Output for each game, output the number of rounds of the game followed by the amount of candy each child ends up with, bot h on one line.
