Provide a solution to the infinite classification of PHP, thank you very much! Reply to discussion (solution) True No limit exists only in theoryBecause all the node information must be stored in the media, and the capacity of the media is limitedSo "infinite pole classification" means maximizing in a limited range.Based on this understanding, different schemes can be selected according to the maximum l

PHP implements an infinite-level tree to achieve the two-level ability of the main menu. You can also develop the message board when you get the parent comments under the child comments!

Tags: unlimited data coverage 1. assume that you want to receive a lot of (or even unlimited) data, but the data has a range: for example, if you want to read the data sent by the serial port, the data range is 0x00-0xff. 2. If an array or container is directly defined for receiving, unlimited memory is required. This method is not feasible. 3. an ingenious method is to define an array (data [0xff + 1]) that covers the size of the required data range, but when receiving a data, it is subscrip

. While a player place a new stone such that its chain immediately has no liberty, this chain willBe captured at once unless this action will also capture one or more enemy's chains.
