1. Given an input with 6 bits: input=001101 and a permutation table P shown below. Please compute the output after the permutation.

2.

3. Given an input with 6 bits: input=0011 and an expansion table E shown below. Please compute the output after expansion.

Please answer all three parts, and I'll upvote; I'm so confused by permutation, inverse, and expansion.

P= \begin{tabular}{|l|l|l|} \hline 3 & 2 & 4 \\ \hline 1 & 6 & 5 \\ \hline \end{tabular} Given a permutation table P1 and P2 shown below, please compute their inverse permutations P11 and P21. P1=4123 E= \begin{tabular}{|l|l|l|} \hline 3 & 2 & 4 \\ \hline 1 & 3 & 4 \\ \hline \end{tabular}
