Tl;dr - just perform the operation against the database, and save the result to a text file.

• You can use any programming language you’d like.
• You can use the Internet as much as you’d like (without cheating.)
• We don’t care much about performance.
• Tests are optional (but correction will probably be taken into consideration.)

You need two files (other files can be ignored.):

• shapes.db
• operations.data

It’s the database, stored as a file.

There’s two columns, separated by a pipe “|” symbol.

• The first column is the id of the row.
• The second column are points on a 2D coordinate plane
  • Points are separated by a semi-colon “;”
  • The x position is before the comma, y position is after it.
  • There’s at most 7 points for a given shape, and minimum 3.
  • You can safely assume that each number in the point is less than 32 bits in size.
  • The points themselves having no real meaning or sort order.

It’s the operations to be performed against the database.

• The amount of columns are variable depending on the operation.
  • The first column is the operation to be performed
    • Operation: delete-shape (delete the shape)
    • Operation: create-shape
      • Create a new shape, it’s points are listed in the last column.
    • Operation: add-point
      • Append the point onto the list of points for that shape.
    • Operation: delete-point
      • The last column is the index of the point to delete (zero indexed.) So, if the last column is a 3, find the shape in the database, and delete the fourth point.
  • The second column is the id
    • For add and delete, this is the shape to modify.
    • For create-shape, this should be the id of the new shape.
• To make things easier, you can safely assume that there’s no more than one operation per shape (meaning: ids are distinct within operations.data)

1. Read in the database.
2. Print (to the console) the counts of each shape (triangles, squares, pentagons, etc.) (nothing pretty needed, but display their counts.)
   • Where a triangle has 3 points, square has 4 points, pentagon has 5 points, etc.
3. Perform the operations against the data.
4. Repeat step 2 – meaning reprint the count of each shape.
5. Print the updated database to a file like “updated.db”.
6. Send us your code and the updated db.
