3. Consider the binary search tree built by inserting the following sequence of integers, one at a time: 5, 4, 7, 9, 8, 6, 2, 3, 1 Which method below will properly remove node 4 from the binary search tree? Find the in order predecessor (IOP) of node 4, which is node 3. Remove node 3 from the tree by setting the right pointer of its parent (node 2) to point to the node pointed to by the left pointer of node 3. Then copy the key and any data from node 3 to node 4, turning node 4 into a new node 3, and delete the old node 3. Set the left pointer of node 5 to nullptr, and then delete node 4.

TUTORIAL: Conducting Sphere and Electric Potential Consider a solid conducting sphere of radius R and total positive charge Q, as shown. The overall goal is to calculate both the electric field $E(r)$ and the electric potential $V(r)$ for all $r$ (i.e. in different regions) and then plot on the axes below. \begin{itemize} \item First, please review with your teammates how you would use Gauss's Law to find the electric field, starting at the center in the region $r < R$. $r < R:$ $\vec{E}(r) = 0$ $r > R:$ $\vec{E}(r) = k \frac{Q}{r^2}$ radially out \item Then, integrate the electric field to find the electric potential, starting \textquotedblleft from infinity\textquotedblright in the region $r > R$, using the formula: $\Delta V = - \int \vec{E} \cdot d\vec{s}$ $r > R:$ \item Next, integrate the electric field to find the electric potential, in the region $r < R:$ $r < R:$ \item Note that the electric field is not the same as the electric potential. How do the graphs and the expressions differ? What are the differences between the way you calculate each? \end{itemize}
