Now I'll write a Python script to solve this problem. The key insight is that the operations allow transforming elements in S to other values based on the rules: from x, you can go to x+k or |x-k|. The problem reduces to checking if the multisets S and T have the same elements when grouped by their "equivalence classes" under these operations.

Let me create a solution:

→ write_file({"path": "/workdir/solve.py", "content": "import sys\nfrom collections import defaultdict\n\ndef get_equivalence_class(x, k):\n    \"\"\"\n    Returns a canonical representative for the equivalence class of x under\n    the operations: x -> x+k or x -> |x-k|\n    \"\"\"\n    # The equivalence class can be thought of as all numbers reachable via\n    # adding/subtracting k, but also absolute values…)
