使用qt creator结合下面代码实现可视化：#include <iostream> #include <cstring> using namespace std; int m; int* nums = new int[m]; int* cnums = new int[m * 8]; class Solution { public: int singleNumber() { int result = 0; for (int i = 0; i < m; i++) { result = result ^ nums[i]; } return result; } }; int main() { int n = 0; while (cin>>m) { if (m == 0) { break; } for (int i = 0; i < m; i++) { cin >> nums[i]; } Solution a; cnums[n] = a.singleNumber(); n++; } cout << endl; for (int i = 0; i < n ; i++) { cout << cnums[i] << endl; } delete[] nums; delete[] cnums; return 0; }

以下是使用Qt Creator可视化的示例代码：

main.cpp:

#include "mainwindow.h"
#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
    return a.exec();
}

mainwindow.h:

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = nullptr);
    ~MainWindow();

private slots:
    void on_calculateButton_clicked();

private:
    Ui::MainWindow *ui;
};

#endif // MAINWINDOW_H

mainwindow.cpp:

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <iostream>
#include <cstring>

using namespace std;

int m;
int* nums = new int[m];
int* cnums = new int[m * 8];

class Solution {
public:
    int singleNumber() {
        int result = 0;
        for (int i = 0; i < m; i++) {
            result = result ^ nums[i];
        }
        return result;
    }
};

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
}

MainWindow::~MainWindow()
{
    delete ui;
    delete[] nums;
    delete[] cnums;
}

void MainWindow::on_calculateButton_clicked()
{
    QString inputString = ui->inputEdit->toPlainText();
    QStringList inputList = inputString.split("\n");

    int n = inputList.size();
    for (int i = 0; i < n; i++) {
        m = inputList[i].toInt();
        if (m == 0) {
            break;
        }
        for (int j = 0; j < m; j++) {
            i++;
            nums[j] = inputList[i].toInt();
        }
        Solution a;
        cnums[i] = a.singleNumber();
    }

    QString outputString;
    for (int i = 0; i < n ; i++) {
        outputString += QString::number(cnums[i]) + "\n";
    }
    ui->outputEdit->setPlainText(outputString);
}

mainwindow.ui:

在Qt Creator中使用设计器设计界面，添加两个TextEdit和一个PushButton，并分别命名为inputEdit、outputEdit和calculateButton。

注意：使用完nums和cnums数组后需要delete[]释放内存，否则会存在内存泄露问题。
