2. Move all elements in the list that are odd to the front of an even-numbered node and ensure that the order of the odd numbers is constant and the order of the even numbers is the same. Example:Order of the linked list after the order of the Swap list4→5→3→1→2 ==> 5→3→1→4→21 ==> 1 (linked list contains only one eleme

Introduction Gray code, a coding scheme proposed by Frank Gray, a scientist at Bell's laboratory decades ago, was mainly used to transmit signals to prevent errors. In addition to applications in communication and hardware design, Gray code is also widely used in computer-related science, such as generating all subsets of a set in order. Gray Code generates all

Subsets: generates all subsets of a series in ascending order. (1) assuming that the elements of the series are not repeated, for example, [4, 2, 3], we can see that there are a total of 2 ^ 3 = 8 subsets, and an empty set is added; (2) sort the series to facilitate the generation of sub-sets in ascending order [2, 3, 4]; (3) Each subset corresponds to a binary v
