Search A Grid

Write search_grid(grid: list[list[int]], target: int) -> tuple[int, int] that returns the (row, col) position of the first cell equal to target, scanning row by row and left to right with the two given loops, or (-1, -1) when the grid does not hold it. Do NOT write a main block or any top-level test code; the tests construct the calls. Input: the number of rows, then one line of space-separated integers per row, then the target; the tests build the grid and print the tuple your function returns.
