ring buffer - overwrite function - Correct code link this time.

Question

I am having issues with the overwrite function of the circular buffer file. It keeps returns an empty buffer on some test runs. What am I missing?

Answer 1

I guess by " returns an empty buffer on some test runs" you are referring to the read operation after an overwrite.

I reckon, overwrite means to be able to write despite a full buffer. In that case I suppose you need to advance the read head should read == write after the write operation. Otherwise, if you look at your condition in read, read == write will be interpreted as empty buffer. Note, however, only to advance the read head if the write operation actually does overwrite the current read head.

Ani Jona I have corrected the issue the code passes all the test put against it now. Thanks for the help.

Answer 3

You're welcome 🙂 What test sets are you testing against? 🤔 That does not look like some competetive programming task 🤔

I am learning using Sololearn, Exercism, codewars and books. The test set for this exercise was from:

Exercism's Unity test.

I'm not competitive just trying to learn on my own.
