Could anybody share a C solution?

    Whatever I return,
    It shows that what I returned is [],
    I just don't know why.

    And what confuses me very much is that the parameter *returnSize is 0...

    You need to write returnSize, so that the judge knows how large your array is. That's why you get a pointer to it.
