How to restore apfs partitions?

Question

Data recovery

When installing OS Ubuntu on an external hdd drive, I did not find that the wrong disk was selected.
As a result, sda (macbook disk) was partitioned into new partitions
. Is it possible to return the disk structure (Knowing what it was) and how to do it?
It is necessary that all files remain in their places, since they were not overwritten and the partitions were not formatted (I think so)

Answer 1

in theory, you can create partitions in fdisk without creating a file system
