I have a question for you!Can you help me?

Hello, have a great weekend! at 1590 lines of code
the ds.bplus.bptreehandleLeafNodeRedistributionOrMerging.BPlusTree#handleLeafNodeRedistributionOrMerging method，I don't quite understand this condition，
code:

int snum = canRedistribute(splitNode);
if (snum > 0) {
  code of redistributing next node with elements from split
}

method canRedistribute is to determine whether a node will still be greater than or equal to M / 2-1 after removing a Key. However, the condition for entering the current method is that the number of keys of the node must be less than or equal to M / 2-1,So I don't think this greater than 0 condition is going to hold, What do you think?I am looking forward to your reply! (^_^)

Hi, not sure I follow... canRedistribute returns a count not a boolean, so this will hold in some instances and as required. If you want to find one such instance during execution either put a breakpoint in your IDE at that branch and observe during execution or uncomment the stdout prints there are in the code.

I do not have time to provide detailed implementation details, so you'll have to figure those out yourself. Unless of course there is a bug... if so, feel free to re-open the issue.
