The Really Neato Calculator Company, Inc. has recently hired your team to help
design their Super Neato Model I calculator. As a computer scientist you suggested
to the company that it would be neato if this new calculator could convert among
number bases. The company thought this was a stupendous idea and has asked your
team to come up with the prototype program for doing base conversion. The project
manager of the Super Neato Model I calculator has informed you that the calculator
will have the following neato features:
It will have a 7-digit display.
Its buttons will include the capital letters A through F in addition to the
digits 0 through 9.
It will support bases 2 through 16.
The input for your prototype program will consist of one base conversion per
line. There will be three numbers per line. The first number will be the number
in the base you are converting from. The second number is the base you are converting
from. The third number is the base you are converting to. There will be one
or more blanks surrounding (on either side of) the numbers. There are several
lines of input and your program should continue to read until the end of file
The output will only be the converted number as it would appear on the display
of the calculator. The number should be right justified in the 7-digit display.
If the number is to large to appear on the display, then print ``ERROR'' (without
the quotes) right justified in the display.
