buildMatrix function

I am not able to understand BuildMatrix function what its doing. You also not explained it in your video.

Can you guide me in right direction about what this function is doing.

Wrong answer for an testcase (java)

https://github.com/Sunchit/Coding-Decoded/blob/master/August2022/Java/PoorPigs.java

The one liner ans in java seems to give wrong answer for following case:

Buckets = 125
minutesToDie = 1
minutesToTest = 4

expected o/p = 3
o/p = 4

Could someone explain why so?
