COINS  Bytelandian gold coins
In Byteland they have a very strange monetary system.
Each Bytelandian gold coin has an integer number written on it. A coin n can be exchanged in a bank into three coins: n/2, n/3 and n/4. But these numbers are all rounded down (the banks have to make a profit).
You can also sell Bytelandian coins for American dollars. The exchange rate is 1:1. But you can not buy Bytelandian coins.
You have one gold coin. What is the maximum amount of American dollars you can get for it?
Input
The input will contain several test cases (not more than 10). Each testcase is a single line with a number n, 0 <= n <= 1 000 000 000. It is the number written on your coin.
Output
For each test case output a single line, containing the maximum amount of American dollars you can make.
Example
Input: 12 2 Output: 13 2
You can change 12 into 6, 4 and 3, and then change these into $6+$4+$3 = $13. If you try changing the coin 2 into 3 smaller coins, you will get 1, 0 and 0, and later you can get no more than $1 out of them. It is better just to change the 2 coin directly into $2.

@selectaman take input each time and check with the length of the input, if it is zero than stop else continue till 10

be careful while taking inputs

Why is map working to store the data and not arrays? When I am using arrays to store the data, it is giving SIGKILL but for map it's running smoothly?

just use recursion + map in cpp

It was little confusing 1 gold coin = 1 $, I considered any gold coin to be worth 1$.... apparently it was a 2$ if it was labeled 2 on it

Can be done via recursion too!!!
