Problem Statement

Background

In one busy Australian household both parents have been working from home during lockdown while also home schooling their three children (triplets).

Each day the children's teacher assigns a list of tasks for them to complete between them. Each task is assigned some points based on difficulty.

The parents are keen that each day each child completes the same number of points so as not to fall behind. And also to stop the constant bickering about who does more/less work :)

For example on Monday the teacher assigned:

Task A: 5 points
Task B: 4 points
Task C: 1 point
Task D: 2 points
Task E: 7 points
Task F: 8 points
Task G: 3 points

These tasks can be split amongst the triplets like so:

Child 1: Task D (2 points) + Task F (8 points) = 10 points
Child 2: Task A (5 points) + Task B (4 points) + Task C (1 point) = 10 points
Child 3: Task E (7 points) + Task G (3 points) = 10 points

The children cannot work on the same task. That would require the negotiation skills of a UN diplomat.

The family needs a way to quickly assess if the tasks can be divided amongst all the children so they each get the same number of points.

If the tasks fail to be split between the three children they will send them back to the teacher and ask for a new set of tasks.

Challenge

The challenge is to write some code that will take any given list of tasks with associated points and output No if the tasks can't be split with points divided evenly between the three children; and output Yes plus the tasks with points for each child if they can.
