Question
Consider the following recursive algorithm for a tree.
get InternalNodes (v, s) {
if (v has at least one child) {
s.push (v)
for each child of v
***BLANK***
}
return s
return s
If we call get InternalNodes () and pass as input the root of a tree T as well
an empty stack, we expect to receive back a stack containing all the internal nodes
of the tree T.
Which of the following statements correctly completes the algorithm above?
S
getInternalNodes (child, s)
return getInternalNodes (child, s)
s.push (getInternalNodes (child, S))
get InternalNodes (child, s)
=
