Please format the temporary memory too.
Ideally something like

temp_memory: [[1,2,3][1,2]]
real_memory: [[1,2]]

should look like this:

-1:0 : 1
-1:1 : 2
-1:2 : 3
-2:0 : 1
-2:1 : 2
0;0 : 1
0:1 : 2

Suggested change

writeln!(f, " {},{} : {}", i, j, cell)?;

writeln!(f, " ({i},{j}) : {cell}")?;

We could avoid making distinctions between real and temporary memory and just pritnt them out as a single memory. Temporary segments can be identified by their negative index

Remember that temporary memory segment indexes start from -1, but we store them from 0 (cuz vec). So when printing out the temporary addresses we should be printing -(i + 1) instead of i

I dont think this is necessary, the user already knows its the memory being displayed if they print the memory

These symbols make it look like a Debug rather than a Display, we could avoid them
