In the movie "Die Hard 3", Bruce Willis and Samuel L. Jackson were confronted with the following puzzle. They were given a 3-gallon jug and a 5-gallon jug and were asked to fill the 5-gallon jug with exactly 4 gallons. This problem generalizes that puzzle and saves the human solvers from the anxiety such puzzles can create... .

You have two containers, A and B, and an infinite supply of water. There are three types of actions that you can use: (1) you can fill a jug, (2) you can empty a jug, and (3) you can pour from one jug to the other. Pouring from one jug to the other stops when the first jug is empty or the second jug is full, whichever comes first. For example, if A contains 5 gallons of water and B contains 6 gallons of water but has a capacity of 8 gallons, then pouring from A to B leaves B full and 3 gallons in A.

A problem is given by a triple (Ca,Cb,N), where Ca and Cb are the capacities of the jugs A and B, respectively, and N is the goal. The solution is the shortest sequence of steps that leaves exactly N gallons in jug B; if there are more than one shortest sequence, operations higher up on the following list are to be preferred (when possible), leaving a single solution. The possible steps are

fill A

fill B

empty A

empty B

pour A B

pour B A

success

where "pour A B" means "pour the contents of jug A into jug B", and "success" means that the goal has been accomplished.

You may assume that the input you are given does have a solution.

**Input Format**

Input to your program consists of a series of input lines each defining one puzzle. Input for each puzzle is a single line of three positive integers: Ca, Cb, and N. Ca and Cb are the capacities of jugs A and B, and N is the goal. You can assume 0 < Ca <= Cb and N <= Cb <=1000 and that A and B are relatively prime to one another.

**Required Output Format**

Output from your program will consist of the shortest series of instructions from the list (and priority) given above which will result in jug B containing exactly N gallons of water. The last line of output for each puzzle should be the line "success". Output lines start in the first column and there should be no empty lines nor any trailing spaces.
