[FEATURE] improve the naming of variables

[haru02w]

Detailed description

The variable names used in sorting/merge_sort.c is really confusing. Please, use more useful names:
int *aux_array instead of int *b

Context

Sorry, I cannot understand what the code is doing

Possible implementation

No response

Additional information

No response

This seems like a very reasonable request and should be handled at review time to ensure no code with unintelligible variable name can get through.
as for ore-existing code we must refactor them if you want to you could start on it.
or point out some of the ones that need immediate attention and are very critical
