Whether a single-chain table is intersection (Java version), single-chain javaQuestion: A single-chain table L1 and L2 with two leading nodes determines if they are intersecting (whether they have the same nodes)Solution:L1 and L2 are empty.Because a single-chain table may have loops, we can discuss them in three cases.1. There is no ring in L1 and L2, so you can

Technical solution for layer-2 interconnection between data centers

In traditional Data Center Server area network design, the L2 network is usually limited to the network convergence layer. By configuring VLANs for cross-aggregation switches, the L2 network can be extended to multiple access switches. This solution provides flexible scalability for the server network access layer. In recent years, high-availability cluster technology and dynamic migration technology of vir

, the price of flash memory is higher than that of mechanical hard disks. However, from the perspective of the overall cost, all flash memory is actually relatively cheap. First, because flash memory is the main force in the future, manufacturers have invested a lot in this technology, and the flash memory price is continuously decreasing. In the future, it will definitely fall to a relatively reasonable price. Second, flash memory has obvious advantages in terms of the cost of purchase and late

21. Merge Two Sorted Lists, mergesorted

21. Merge Two Sorted Lists, mergesorted The question comes from leetcode. The requirement is to splice two sorted linked lists into an ordered linked list. The linked list structure is as follows: public class ListNode{ int val; ListNode next; ListNode(int x){ val=x; } } As follows, a rectangle becomes a node, and a linked list has at least one node. Method 1: first create a new linked list L, compare the Val of the current L1 and

Python's example of merging and sorting two sequential tables

Suppose there are 2 sequential tables L1, L2, how efficient the 2 lists are merged and maintained in an orderly state, where the default ordering is the positive order. The idea is relatively simple, which is to compare the first element of L1 and L2 head in turn, will be smaller than a new list, and so on, until all the elements are placed in the new list. Consider 2 lists L1 = [2],

[Lintcode] Add Numbers I && II

ADD NumbersYou have both numbers represented by a linked list, where each node contains a single digit. reversethe digits is stored in order, such the 1 's digit is at the head of the list. Write a function that adds the numbers and returns the sum as a linked list.ExampleGiven 7->1->6 + 5->9->2 . That's, 617 + 295 .Return 2->1->9 . That's 912 .Given 3->1->5 5->9->2 and, return 8->0->8 .Solution:It is simple to add, to see a linkedlist again, and then to consider the carry, a carry count, the nu

Assuming that there are 2 sequential table L1, L2, how to efficiently combine 2 lists and maintain an orderly state, where the default sort is positive sequence. The idea is relatively simple, but is to compare L1 and L2 The first element of the head, will be smaller than a new list, and so on, until all the elements are placed in the new list.

Example of how Python merges and sorts two ordered lists

This article mainly introduces Python's examples of merging and sorting two ordered lists. The final code is constantly optimized and the small Editor is very satisfied, for more information about how to merge two lists with high efficiency and keep them in order, the sorting is positive by default. The idea is relatively simple. It is nothing more than comparing the first element in l1 and l2 headers in sequence, placing the smaller one in a new lis

Calculate the cross product of a straight line intersection

General Equation Method: The general equation of a straight line is f (x) = AX + by + c = 0. Now that we know the two points of a straight line, assuming (x0, y0), (x1, Y1), we can get a = y0-Y1, B = x1-x0,C = x0y1-x1y0. Therefore, we can represent the two straight lines F0 (x) = A0 * x + B0 * Y + C0 = 0, F1 (x) = A1 * x + B1 * Y + C1 = 0 The intersection of the two straight lines should meet A0 * x + B0 * Y + C0 = A1 * x + B1 * Y + C1 This can be introduced X = (B0 * C1-B1 * C0)/d Y = (A1 * C0
