Where is the mistake in my code

help

Hello!

I’ve manually tried to verify my code with several custom test cases and my output was same as expected output, but still I am getting WA.

Here’s my submission

I am unable to spot the error as all the custom test cases that I ran were giving me correct output.

Consider the following test case :-

1
3 5
5 5 3
1 4 1
3 2 2

Correct Answer is 31
Solution:- Consider the FIrst and Third Question, total time taken to learn these questions is 3 + 2 = 5 and the total points earned are 5*5 + 3*2 = 31.
But your code seems to give answer as 29.
