#CSV Challenge
Write a Ruby program to first assemble a single set of records by parsing data from 3 different file formats and then display these records sorted in 3 different ways.
###Guidelines
We hope that this exercise will allow us to evaluate your skills as a developer. The qualities that we pay special attention to are:
- Simplicity/elegance of design
- Adherence to good software engineering principles
- Maintainability (clean, easy to understand code)
- Effective use of the standard library
- Use of unit tests
###Input Data
A record consists of the following 5 fields: last name, first name, gender, date of birth and favorite color. You will be given 3 files, each containing records stored in a different format (sample/comma.txt, sample/pipe.txt, sample/space.txt).
- The pipe-delimited file lists each record as follows:
lastName | firstName | middleInitial | gender | favoriteColor | dateOfBirth - The comma-delimited (csv) file looks like this:
lastName, firstName, gender, favoriteColor, dateOfBirth - The space-delimited file looks like this:
lastName firstName middleInitial gender dateOfBirth favoriteColor
You may assume that the delimiters (commas, pipes and spaces) do not appear anywhere in the data values themselves. Write a Ruby program to read in records from these files and combine them into a single set of records.
###Display Requirements
-
Create and display 3 different views of the recordset (see
sample/expected_output.txt):- Output 1 – sorted by gender (females before males) then by last name ascending.
- Output 2 – sorted by birth date, ascending.
- Output 3 – sorted by last name, descending.
-
Ensure that fields are displayed in the following order: last name, first name, gender, date of birth, favorite color.
-
Display dates in the format M/D/YYYY.
