About the P4: Check Subtree category

(Replace this first paragraph with a brief description of your new category. This guidance will appear in the category selection area, so try to keep it below 200 characters.)

Use the following paragraphs for a longer description, or to establish category guidelines or rules:

  • Why should people use this category? What is it for?

  • How exactly is this different than the other categories we already have?

  • What should topics in this category generally contain?

  • Do we need this category? Can we merge with another category, or subcategory?

I am getting compile errors for checksubtree.cpp file itself. As the the file is not visible to us can you check the errors in it?
