"# Exercise: Match the tarot cards!\n",
"\n",
"Given 2 decks of tarot cards, `deck1` and `deck2`, find all the matching pairs. The output should be a set of tuples `(idx1, idx2)` for every matching pair in `deck1`, `deck2`.\n",
"\n",
"For example:\n",
"```\n",
"deck1 = ['C', 'B', 'A']\n",
"deck2 = ['A', 'C', 'B']\n",
"```\n",
"\n",
"should return (in no particular order):\n",
"\n",
"```\n",
"{(0, 1), (1, 2), (2, 0)}\n",
"```\n",
"\n",
"1. Write an algorithm to match the tarot cards\n",
"2. Compute the Big-O complexity of your algorithm\n"
