You will have to write your own logic to do it.

You will need a loop to navigate to each value in the array after you have sorted the results. Declare a string variable and concatenate the required parts. The value in the string will be complete only when you find 3 subjects for the same id.

It isn't very hard. You just need to start trying. See what I have suggested and start implementing it. The debugger will come handy in doing this. Come back when you have tried and have 'specific' issue.

Good luck!

I agree with Ankur. Write some code and whenever you have a specific problem, come back here, click "improve question" and explain what is not working as expected.
