Just-A-Regular-Task.

Its quite boring, lets do some tasks.

---

Write a console application that takes 3 command line arguments in the format:

input= alpha= numer=

The application should read the input argument file and output its results to the alpha and numer files.

Parts of the input file contains information in the following format:

[(<item><item>)(<item>)][()]

Where, is the name of a group containing items and is the value of the item. ‘[‘ and ‘]’ characters contain groups, and ‘(‘ and ‘)’ contain items within a group. Items can be alphabetic, alphanumeric or numeric, for example; zebra, word3 or 986.

The groups and items need to be extracted from the input file, processed, and written to the output files.

Output:

• The app should write 2 output files, one containing all the alphanumeric items, and another containing all the purely numeric items.
• The output items should be listed under their group name, each on a new line and indented by 1 space.
• There should be an empty line between groups.
• Items must be listed in increasing numerical and alphabetical order per group.
• Items should be listed only once per group even if there are duplicates in the input file.
• Groups must also be listed in increasing alphabetical and numerical order per file.
• New line and other control characters in the input file must be ignored / not included in the output.
• Duplicated groups should be listed just once per output file including items from both.
• Do not include empty items.

Example input and resulting output alpha and numer files

input file:

56T[zebra(foolish\75\toledo\wisconsin\56)horse(\5\alien \yelling\hello\alien\88\felt\79)]garbage[zebra(great\44\43\sold\)byfar(1\3\2\5\m8T)]welling

Resulting alpha ouptut file:

byfar m8T

horse alien felt hello yelling

zebra foolish great sold toledo wisconsin

Resulting numer output file:

byfar 1 2 3 5

horse 5 79 88

zebra 43 44 56 75
