Minesweeper Board Generation and Rendering

Implement a function to generate and print a Minesweeper board. Given board size m x n and number of mines k (k <= m*n), randomly place k mines on distinct cells. Then output an m x n grid where: Mine cells are represented by '*'. Non-mine cells contain the number of mines in the 8 neighboring cells (including diagonals), from 0 to 8. Requirements: Mine placement must be random and without duplicates. Output may be a 2D array or printed row by row. Constraints 1 <= m, n <= 200 0 <= k <= m*n Example (illustrative; randomness means output may vary) Input: m=3, n=4, k=2 Possible output: * 1 0 0 2 2 1 0 * 1 0 0 Example Input 3 4 0 0 Output 0 0 0 0 0 0 0 0 0 0 0 0
