git bisect is a tool that allows you to find an offending commit. … If you can find a commit where the code works properly and a commit where it doesn’t, you don’t have to trace down the offending commit by hand; git-bisect will do that for you.

What does git bisect reset do?

git bisect reset is how you stop bisecting. By default it will reset the HEAD to where it was before you started, although you can also use git bisect reset <commit> to go to that one instead.

How do I remove a bad commit in git bisect?

Use git log to check the previous commits. Use Git Bisect to find the commit in which line 2 is changed from ‘b = 20’ to ‘b = 0.00000’. Remove the bad commit by using Git Revert. Leave the commit message as is.
