Hello! The fails were due to two lines commented by mistakes. Here are the two modifications to apply https://github.com/Nanored4498/ton/commit/4d7a7ac35a39a4485b5c1db02d3bd02c72b775e1
. It turns out, it was not sufficient (still one remaining fail). It
was due to the fact I was using two different add_used_storage with
different graph traversals. I've corrected it by just moving one line in
this second commit https://github.com/Nanored4498/ton/commit/556b3d133d9fac4b3354810e992df0eb0d8e35e8

In case here is a new patch file https://drive.google.com/file/d/10fi6poiuBmtkMQzsxQ_h3McX7w_T8dx_/view?usp=sharing
I
hope it could be consider, as It took me quite some time to optimize
the code and it is probably the fastest solution. I would be sad if my
solution couldn't be considered for such a small mistake. I would be
very grateful if you could relaunch the evaluation with these small
changes :)
