Copy constructor binary search tree c++


Now a few things happen copy constructor binary search tree c++ I try run this. This is strange to me since I'm calling a recursion on every node, since I start at the root and then call it on the left and right. This means changes to this variable are never seen by the caller. A more common idiom is to use the function return value: I'm not sure how else to look for the problem.

I'm not sure how else to look for the problem. Stack Overflow works best with JavaScript enabled. Then recursively copying the subtrees is very simple:. Email Sign Up or sign in with Google. A more common idiom is to use the function return value:.

I tried writing out the process on paper, visually planning out how it would copy the original tree but to me it seems like a logical process and can't find where it could get lost. Your declaration of treeNew creates a call-by-value parameter.

Therefore the changes you're making copy constructor binary search tree c++ this variable are never seen by the caller, and what you're getting for the tree copy is junk.

A more common idiom is to use the function return value: First, it doesn't copy all of the nodes, and will copy a different amount each time. Then recursively copying the subtrees is very simple:. By posting your answer, you agree to the privacy policy and terms of service.
