c++ – LeetCode 212: Word Search II

I’m posting my code for a LeetCode problem copied here. If you would like to review, please do so. Thank you for your time!

Problem

Given a 2D board and a list of words from the dictionary, find all
words in the board.

Each word must be constructed from letters of sequentially adjacent
cell, where “adjacent” cells are those horizontally or vertically
neighboring. The same letter cell may not be used more than once in a
word.

Example:

Input:  board = (   
('o','a','a','n'),   
('e','t','a','e'),  
('i','h','k','r'),   
('i','f','l','v') 
) 
words =
("oath","pea","eat","rain")

Output: ("eat","oath") 

Note:

  • All inputs are consist of lowercase letters a-z.
  • The values of words are distinct.

Code

#include <vector>
#include <string>
#include <set>

class Solution {
    static constexpr unsigned int A_LOWERCASE = 'a';
    static constexpr unsigned int ALPHABET_SIZE = 26;

private:
    class TrieNode {
    public:
        std::vector<TrieNode *> children;
        bool is_word;

        TrieNode() {
            is_word = false;
            children = std::vector<TrieNode *>(ALPHABET_SIZE, NULL);
        }
    };

    class Trie {

        }

        Trie(const std::vector<std::string> &words) {

            for (unsigned int index = 0; index < words.size(); index++) {
                set_word(words(index));

            structured_found_words.push_back(found_word);
        }

        return structured_found_words;
    }

private:

        if (parent->children(board(row)(col) - A_LOWERCASE) != NULL) {
            word = word + board(row)(col);
            parent = parent->children(board(row)(col) - A_LOWERCASE);

            if (parent->is_word) {
                structured_found_words.insert(word);
            }

            char alphabet = board(row)(col);
            board(row)(col) = ' ';
            depth_first_search(board, row + 1, col, parent, word, structured_found_words);
            depth_first_search(board, row - 1, col, parent, word, structured_found_words);
            depth_first_search(board, row, col + 1, parent, word, structured_found_words);
            depth_first_search(board, row, col - 1, parent, word, structured_found_words);

    };
};

Reference

LeetCode has a template for answering questions. There is usually a class named Solution with one or more public functions which we are not allowed to rename. For this question, the template is:

class Solution {
public:
    vector<string> findWords(vector<vector<char>>& board, vector<string>& words) {
        
    }
};

magento2 – Magento 2.1.2: URL add directory names and return page 404 not found

I migrated my magento store from the local to the server, then I changed core_config_data road of https://example.com/ and I have executed all the commands like upgrade, deployment and any other cleaned cache.
But when I try to run my URL, it adds two root folders with it and likes https://example.com/_web/_xyz and I get the default 404 page from Magento.
When I clean up these 2 URL files, it works fine, but for the first time, I have a problem.
I checked my url logo its okay all right but problem first.
Please help me out.
A little help will be greatly appreciated.
Thanks in advance

Mac App – Teorex PhotoStitcher 2.1.2 macOS | NulledTeam UnderGround

Size of the file: 15 MB
PhotoStitcher automatically combines overlapping photos to produce a perfect panoramic image.

Visit our tutorials page and see for yourself how easy it is to do in a few simple steps. Does creating a perfect panorama require professional skills and a high-end camera? Not necessarily. With PhotoStitcher, you can assemble multiple photos into a picturesque panoramic image. The program smoothly combines photos of different resolutions, different angles of view and even different perspectives in a perfectly aligned panorama representing breathtaking landscapes, monumental churches or mountains to skyscrapers so difficult to integrate into one frame.

Take overlapping photos and PhotoStitcher assembles them all

Make sure each photo overlaps about 30-50% of all other adjacent photographs. Sometimes a standard sized photo just is not enough to capture the magnificence of a certain landscape. A horizontal panorama would better reflect the beauty of the coastline, while a panoramic vertical image would capture a magnificent mountain view. PhotoStitcher helps you create beautiful panoramic images from superimposed photos in case you have missed the opportunity to take a panoramic photo and only have scattered photos with varying perspective, angle and zoom

Trading 212 – Free Stocks worth up to £ 100 / $ 100 / € 100

Would you like to get a free share worth up to £ 100 / $ 100 / € 100?

Create an account Trading 212 Invest using THIS REGISTRATION LINK and we both have a free share!
Unfortunately, you can only make this offer by invitation.

Follow these steps …

1. Click the link above and click open an account. When you select an account type, click on the type of INVEST account, fill out the form with all your information.

2. Wait until your account is activated, this usually happens automatically, but you may have to go through a manual check. Once logged in, click on CHAT, select Account Activation and follow the required steps.

3. You must deposit £ 30 / $ 30 / € 30 (I made £ 35 to be sure)

4. Once you have activated and deposited, you will receive your free action within 24 hours. To see what actions you have, check out "Open Positions" at the bottom of your Trading212 screen. You can choose to hold the stock or sell it by clicking on the "X" symbol next to the stock to close the position. Once sold, the money from the sale will go to your account.

You must wait 3-5 business days before closing your position on the stock., I would choose 5 days, so that you do not seem to exploit the system.

If you invest your initial deposit between £ 30 and £ 35, you also get a link that you can share with your friends and make the same promotion. The first 20 friends you invite will receive a free random share that you can leave for an investment or a withdrawal.

5. To withdraw funds, click on your account in the upper right-hand corner of the screen and then choose the "Withdraw Funds" option from the drop-down menu to withdraw your funds from your card / bank account.

If you choose to keep it open, simply swap once every 6 months to avoid inactivity charges. You can also keep the account balance at zero because no idle costs are incurred in this case.

visas – Exemption from the obligation for Article 212 (a) (6) (c) (i)

In 2014, my little boy was born in Arlington Heights (United States). In 2015, I was expelled from Chicago Airport with my wife and my little American citizen boy. I am re visa visitor request in 2017 this time, they give me green paper and ask paid the hospital bill, I paid and send it to the consulate, but not given visa. After I was applied in January 2019 and the consular officer issued me a letter stating that I could not be admitted to the United States under section 212a (6) (c) (i), this meant that I had to surrender. so can you make a waiver for this and also let me know can i get a USA visa after this waiver or not …… ????

visa refusal – Can 212 (a) (6) (c) be appealed?

My wife received a refusal when she applied for an H4 visa for the 4th time and received a refusal code 212 (a) (6) (c) (ii) the Shenyang embassy in China last year.

The explanation given by the embassy is that when she was in F1, she applied a school that had been involved in a fraudulent problem and had already been closed down.

In fact, it's when my wife applied this school well before school had a scandal and she did not enroll in this school at all. She did family shopping and stayed physically in China all year.

Then she came to the United States with me under H4 after our wedding. She has nothing to do with the school anymore.

We found a lawyer who said he could really help us on appeal and who charged me $ 7,500 for the case. In fact, they send an e-mail to the embassy to ask why she was denied and received an answer: "She already has everything she needs to know". Then they told me that they will appeal to the State Department. They said the process is DoS will allow the Embassy to correct their decision and let us wait. (month of waiting without guarantee of answer)

I feel fooled by the lawyer and my money is wasted.
Can someone help?
