Which of the follwing is Not an example of debugging? looking for errors, fixing misspelled commands in programming code solving faulty logic in programming code Upgrading to improve the programming code

Upgrading to imporve the code. Debugging is the process 2where you fix errors and mistakes, not improving it. Debugging is basically fixing glitched and such or finding the block of code in which an error is present and fixing that. So its not a process where one upgrades but rather fixes.
