Hi,

The fuction should work in C.

I need to create a struct for tree with pointer to parent only, without pointers to left & right childs.

The function got two pointers for two childs and printer the shared parent of them.

The function will print the info of the shared parent.

I attached a doc file that show what I want, there is two blue childs that the red parent is the one that the function need to print.

I alse need to know the struct elements.

Sorry for my english.

Thanks alot
