In Chinese currency system, the bills come in 100, 50, 20, 10, 5, 2 and 1 denominations. When you buy something, the money you give to the salesman is a combination of these denominations. If the money you have paid is more than actual price, the salesman will return change with the least number of bills. For example, if you pay one 100-bill and one 50-bill to buy goods worth 123. The salesman should return you three bills: one 20-bill, one 5-bill and one 2-bill. If the salesman has no 5-bill, he would give you five bills: one 20, three 2 and one 1. If the salesman doesn’t have enough petty cash, he can apply any number of 1-bills. If the money you paid is less than the goods’ price, the salesman will refuse this business.

Input

For each test case, the first line contains the price of the goods, the second line contains the money you pay, and the third line contains the money that the salesman has. We present the money with 7 integers, which mean the numbers of 100-bill, 50-bill, 20-bill, 10-bill, 5-bill, 2-bill and 1-bill respectively.

Output

For each case, you should output the type of this transaction, which can be “Refuse”, “Accept”, and “Apply”, then output seven integers denoting the change. If the type is “Refuse”, you should just output seven 0s.
