Expected behavior

The function performs string conversion operations without formatting errors.

Actual behavior

While running the compute_transform_tables function in the min_cost_string_conversion.py script, the following error occurs:

ValueError: Unknown format code 'c' for object of type 'str'

[tianyizheng02]

I'm not sure why the c modifier is there in the code since it doesn't seem to be a valid format code.

This really is something that we should've caught much earlier, but I guess we didn't notice since the code didn't have any unit tests and thus wasn't being run in our workflows. Thanks for the catch!

My pleasure !
