Problem 1: Carpet layingAt first glance, cry, carpet coverage... it seems to be a 2-dims line segment tree. It is so difficult at the beginning. Again, you only need to find a point, make a decisive question, and simulate it. (Note: From the enumeration with a large label to a small one, if there is a carpet that meets the requirements, the output will be returned .)(If the entire article is not completed,

]) Array_chunk () splits an array into multiple arrays, where the number of units per array is determined by size. The number of cells in the last array may be few. The resulting array is a cell in a multidimensional array whose index starts at zero.Setting the optional parameter Preserve_keys to TRUE allows PHP to retain the original key name in the input array. If you specify FALSE, then each result array will be indexed with a new zero-based number. The default value is FALSE.
