Problem L. My Hero Photographia
*****
Problem L:

For Blur operation, we rounded down. I think the test is wrong for negative integers. In my first submission, I calculate -10/9 = -2, but if I calculated -10/9 as -1, I got Accepted.
Round down is worded poorly in the statement --- for negative numbers, -10/9 = -1 is the intended output.

Problem B. Angel Beats
*****
Why is the final output 1? Isn't it 0 mod ... = 0 :thinking_face: ?
:thinking_face:

I left off a line of the sample input on accident -- the 2nd group wasn't empty, but the explanation for the sample case is based on if it was.

The sample case should be updated soon to reflect this.
