  /**
   * In the popular Minesweeper game you have a board with some mines and those cells
   * that don't contain a mine have a number in it that indicates the total number of mines
   * in the neighboring cells. Starting off with some arrangement of mines
   * we want to create a Minesweeper game setup.
   *
   * @param {Array<Array>} matrix
   * @return {Array<Array>}
   *
   * @example
   * matrix = [
   *  [true, false, false],
   *  [false, true, false],
   *  [false, false, false]
   * ]
   *
   * The result should be following:
   * [
   *  [1, 2, 1],
   *  [2, 1, 1],
   *  [1, 1, 1]
   * ]
