Four students are running for president of the Current Events Club: Arthur (A), Brandy (B), Chandra $(C)$, and Darrell (D). The preference ballots for the candidates are shown. Construct a preference table to illustrate the results of the voting.
$$\begin{array}{l}\text{ DBAC DABC DABC DBAC DABC DBAC }\\ \text{ CABD DABC DAAC DABC ACBD DABC }\end{array}$$
$$\text{Unknown environment 'tabular'}$$

Step 1 ：Given the preference ballots for the candidates, we are asked to construct a preference table to illustrate the results of the voting.

Step 2 ：The preference table should show the number of votes each candidate received for each rank (first choice, second choice, etc.).

Step 3 ：We first create a dictionary to store the votes for each candidate.

Step 4 ：We then iterate through the ballots and update the dictionary accordingly.

Step 5 ：The ballots are as follows: ['DBAC', 'DABC', 'DABC', 'DBAC', 'DABC', 'DBAC', 'CABD', 'DABC', 'DAAC', 'DABC', 'ACBD', 'DABC'].

Step 6 ：After counting the votes, we find that the votes for each candidate are as follows: Arthur (A): [1, 8, 4, 0], Brandy (B): [0, 3, 8, 0], Chandra (C): [1, 1, 0, 10], Darrell (D): [10, 0, 0, 2].

Step 7 ：Finally, we construct the preference table based on the votes each candidate received for each rank.

Step 8 ：The preference table is as follows: $$\begin{array}{lcccc}& \text{First Choice}& \text{Second Choice}& \text{Third Choice}& \text{Fourth Choice}\\ \text{Arthur (A)}& 1& 8& 4& 0\\ \text{Brandy (B)}& 0& 3& 8& 0\\ \text{Chandra (C)}& 1& 1& 0& 10\\ \text{Darrell (D)}& 10& 0& 0& 2\end{array}$$

Step 9 ：$\boxed{{\displaystyle \text{The preference table is as follows:}}}$ $$\begin{array}{lcccc}& \text{First Choice}& \text{Second Choice}& \text{Third Choice}& \text{Fourth Choice}\\ \text{Arthur (A)}& 1& 8& 4& 0\\ \text{Brandy (B)}& 0& 3& 8& 0\\ \text{Chandra (C)}& 1& 1& 0& 10\\ \text{Darrell (D)}& 10& 0& 0& 2\end{array}$$
