problem

Recall that if bb is a residue $\pmod{m}$, then the modular inverse of bb is the residue cc for which $bc \equiv 1\pmod{m}$. The table below shows the inverses of the first 9 positive residues modulo 47. \begin{tabular}{c|ccccccccc} bb & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 \\ \hline inverse of b\,b & 1 & 24 & 16 & 12 & 19 & 8 & 27 & 6 & 21 \end{tabular}Find the modular inverse of $35\pmod{47}$. Express your answer as an integer from 00 to 4646, inclusive.
