The missing numbers here are 2 and 9.\n\n2. **Filling in the cells:**\n - R3C6 must be 9 because 5 is already present in the same row.\n - R3C5 must be 5 because 9 is already present in the same row.\n - R4C7 must be 7 because 6 is already present in the same row.\n - R5C7 must be 4 because 7 is already present in the same row.\n - R8C4 must be 9 because 2 is already present in the same column.\n - R9C4 must be 2 because 9 is already present in the same column.\n\n3. **Double-checking the solution:**\n - Verify each filled cell to ensure no Sudoku rules are violated.\n\nAfter filling in the cells, the completed puzzle will look like:\n```\nR1 5 8 3 | 6 2 4 | 1 7 9\nR2 1 4 9 | 8 7 3 | 5 6 2\nR3 6 7 2 | 1 5 9 | 8 4 3\n- - - - - - - - - - - - - - - - - \nR4 3 1 4 | 5 6 9 | 7 2 8\nR5 2 9 6 | 7 1 8 | 4 3 5\nR6 7 5 8 | 4 3 2 | 9 1 6\n- - - - - - - - - - - - - - - - - \nR7 9 2 5 | 3 4 7 | 6 8 1\nR8 4 3 1 | 9 8 6 | 2 5 7\nR9 8 6 7 | 2 5 1 | 3 9 4\n```\n</think>\n<answer>\n[\n [3, 5, 5],\n [3, 6, 9],\n [4, 7, 7],\n [5, 7, 4],\n [8, 4, 9],\n [9, 4, 2]\n]\n</answer>",

Given the hint, we know the empty cells are at R2C5, R2C7, R5C3, and R7C5.\n\n1. **R2C5** can only be `5` or `8` because the numbers `1` through `9` must appear only once in each row, column, and 3x3 grid.

After checking, `5` is not possible as it's already in the grid, so R2C5 must be `8`.\n\n2. **R2C7** can be `5` or `6`, but since R2C5 is `8`, and considering column 7 already has `3` and `1`, and the 3x3 grid already has `6`, R2C7 must be `5`.\n\n3. **R5C3** can only be `3` or `8`. Row 5 already has `25-317964`, Column 3 already has `9`, and the 3x3 grid already has `8`. Since `8` is in the grid, R5C3 must be `3`.\n\n4. **R7C5** can only be `3`, `5`, or `6`.

The missing value is `1`.\n\nTherefore, `R2C2` should be `1`.\n\nFor `R2C4`:\n- Row 2 already contains 6, 1, 7, 4, 2, 3, 5. The missing values are 8, 9.\n- Column 4 already contains 6, 8, 2, 8, 4, 1, 7, 5, 3. The missing values are 9.\n- Sub-grid of R2C4 already contains 6, 1, 8, 7, 4, 5, 2.
