A 2-row GShare predictor is shown below. It has a 2-bit GHR. The least significant bit of the PC is used for indexing into this predictor.  GHR: 10 Index 00 01 10 11 0 10 11 10 00 1 01 01 10 10 The branch PC is 0xEEEE1206. The actual behavior is NT. The branch is predicted as [behavior] (enter T or NT).  Show the updated predictor. Only enter values that change, and enter a dash ‘-‘ (without the quotes) for entries that don’t change.  Index 00 01 10 11 0 [000] [001] [010] [011] 1 [100] [101] [110] [111] The updated GHR is [ghr].
