Question 1: [25 points]
In a country far, far, away during a time long, long ago there lived a king called Keith. Keith
ruled Stonesland and serenaded the people living in this idyllic land with his guitar playing. The
currency used in Stonesland consisted of the following coins: a STONE, a KEITH, a MICK,
and a RON (listed in DECREASING order of monetary value, refer to Figure 1).
Figure 1: The coins used in Stonesland.
The relationship among these coins was decided by the King Keith (quite arbitrarily) to be:
1 STONE = 15 KEITHS
1 KEITH = 20 MICKS
1 MICK = 12 RONS
1 RON = 1 RON ( a RON is sort of like a penny, it is worth the least amount and people keep
throwing them onto the streets of Stonesland much to the annoyance of the King ...)
Write a complete C++ program which will ask the user to input the number of STONE coins, the
number of KEITH coins, the number of MICK coins, and the number of RON coins that she has
in her pocket. The program will then display total value represented by these coins using the
LEAST amount of coins. Typical interaction with the program would be similar to:
"Mick only
