如何优雅的使用clion刷leetcode

安装插件：LeetCode Editor)

插件配置：

这样我们每打开一个项目，就会创建类似的文件

我们的项目结构：

我们在题解文件中导入头文件myHeader.h并将新建的文件添加到cmakelists.txt文件，这样就不会报错了

CMakeLists.txt

cmake_minimum_required(VERSION 3.28)
project(LeetCodeTime)set(CMAKE_CXX_STANDARD 17)# 添加源文件,选择运行的题解
file(GLOB SRC_FILES ${PROJECT_SOURCE_DIR}/leetcode/editor/en/twoSum.cpp)add_executable(LeetCodeTime main.cpp ${SRC_FILES})target_include_directories(LeetCodeTime PUBLIC ${PROJECT_SOURCE_DIR}/include)

修改file(GLOB SRC_FILES ${PROJECT_SOURCE_DIR}/leetcode/editor/en/twoSum.cpp),这样就能调试了~

main.cpp

#include <iostream>
void runProblem();
int main() {system("chcp 65001"); // 支持中文std::cout << "50000个测试用例开始测试!" << std::endl;runProblem();return 0;
}

twoSum.cpp

// 1 Two Sum 2024-07-09 19:44:32
#include "myHeader.h"
//leetcode submit region begin(Prohibit modification and deletion)
class Solution {
public:vector<int> twoSum(vector<int>& nums, int target) {for (int i = 0; i < nums.size(); i++) {for (int j = i + 1; j < nums.size(); j++) {if (nums[j] == target - nums[i]) {return {i, j};}}}return {};}
};
//leetcode submit region end(Prohibit modification and deletion)void runProblem() {Solution solution;vector<int> nums = {2, 7, 11, 15};int target = 9;vector<int> result = solution.twoSum(nums, target);for (int num : result) {cout << num << " ";}cout << endl;
}

例如，我们要调试两数之和这道题,我们就需要实现runProblem，自行设置测试用例，这样通过打断点就能调试了~,注意，这里的runProblem方法是最简单的方法，必要情况下，你可以完善如下功能，创建一个生成测试用例的函数，同时输出与正确答案结果不同的测试用例，至于正确结果，可以直接拿题解的就行。例如如下示例

// 1 Two Sum 2024-07-09 19:44:32
#include "myHeader.h"
//leetcode submit region begin(Prohibit modification and deletion)
class Solution {
public:vector<int> twoSum(vector<int> &nums, int target) {for (int i = 0; i < nums.size(); i++) {for (int j = i + 1; j < nums.size(); j++) {if (nums[j] == target - nums[i]) {return {i, j};}}}return {};}
};
//leetcode submit region end(Prohibit modification and deletion)
// 生成随机数组
vector<int> generateRandomArray(int maxSize, int maxValue) {vector<int> randomArray;// 创建随机数生成器std::random_device rd;// 创建一个指定随机数范围的随机数引擎std::mt19937 eng(rd());std::uniform_int_distribution<int> maxValueEng(0, maxValue);std::uniform_int_distribution<int> maxSizeEng(0, maxSize);// 生成随机数组maxSize = maxSizeEng(eng);randomArray.reserve(maxSize);for (int i = 0; i < maxSize; ++i) {// 数组内没有重复元素int randomValue = maxValueEng(eng);while (find(randomArray.begin(), randomArray.end(), randomValue) != randomArray.end()) {randomValue = maxValueEng(eng);}}return randomArray;
}// 获取随机值
int getRandomValue(int maxValue) {std::random_device rd;std::mt19937 eng(rd());std::uniform_int_distribution<int> maxValueEng(0, 2 * maxValue);return maxValueEng(eng);
}// 比较器
vector<int> comparator(vector<int> &nums, int target) {unordered_map<int, int> numMap;int n = nums.size();for (int i = 0; i < n; i++) {int complement = target - nums[i];if (numMap.count(complement)) {return {numMap[complement], i};}numMap[nums[i]] = i;}return {}; // No solution found
}
// 比较两个数组是否相等
bool isEqual(vector<int> &nums1, vector<int> &nums2) {return nums1 == nums2;
}
// 测试
void runProblem() {int testTime = 50000; // 测试次数int maxSize = 50;    // 数组最大长度int maxValue = 10000;   // 数组元素最大值bool succeed = true;Solution solution;for (int i = 0; i < testTime; ++i) {vector<int> randomArray = generateRandomArray(maxSize, maxValue);int target = getRandomValue(maxValue);vector<int> solutionResult = solution.twoSum(randomArray, target);vector<int> comparatorResult = comparator(randomArray, target);if(!isEqual(solutionResult, comparatorResult)) {cout << "第" << i << "次测试失败!" << endl;cout << "原数组：" << randomArray << endl;cout << "目标值：" << target << endl;cout << "Solution result: " << solutionResult << endl;cout << "Comparator result: " << comparatorResult << endl;succeed = false;break;}}cout << (succeed ? "测试用例全部通过!" : "测试失败!") << endl;
}
