The CCC harp is a stringed instrument with strings labelled A,B,...,T. Like other instruments, it
can be out of tune.

A musically inclined computer science student has written a clever
computer program to help tune the harp. The program analyzes the sounds
produced by the harp and provides instructions to fix each string that
is out of tune. Each instruction includes a group of strings, whether
they should be tightened or loosened, and by how many turns.

Unfortunately, the output of the program is not very user friendly.
It outputs all the tuning instructions on a single line. For example,
the single line AFB+8HC-4 actually contains
two tuning instructions: AFB+8 and
HC-4. The first instruction indicates that
harp strings A, F, and B should be tightened 8 turns, and the
second instruction indicates that harp strings H and C should be loosened 4 turns.

Your job is to take a single line of tuning instructions and make
them easier to read.

Marks

The following table shows how the available 15 marks are
distributed.

There will be one line of input which is a sequence of tuning
instructions. Each tuning instruction will be a sequence of uppercase
letters, followed by a plus sign (+) or minus
sign (-), followed by a positive integer.
There will be at least one instruction and at least one letter per
instruction. Also, each uppercase letter will appear at most once.

There will be one line of output for each tuning instruction. Each
line of output will consist of three parts, each separated by a single
space: the uppercase letters referring to the strings,
tighten if the instruction contained a plus
sign or loosen if the instruction contained a
minus sign, and the number of turns.
