      return tuple(blk_coverage_1d(b, s)[0] for b, s in zip(blk, shape))
docs: Return the maximum shape of an array covered by a block.
  
      :param blk: the N-dimensional shape of the block
      :param shape: the N-dimensional shape of the array
      :return: the shape of the covered region
  
      Example:
  
          >>> max_blk_coverage(blk=(7, 6), shape=(100, 43))
          (98, 42)
