Local Leetcode Code Generator (LLCG)

Overview

Local Leetcode Code Generator (a.k.a., LLCG) is a code generator that generates LeetCode-style code to run locally.

Please feel free to contact me to give any comments or suggestions.

Quick Start

1. Place your LeetCode-style code into code/input.cpp
2. Place your test case into code/input.txt (copy and paste from LeetCode is recommended)
3. Run python main.py
4. code/output.cpp can be run locally!

Example

Two_Sum

First, write your Solution here in code/input.cpp.

class Solution {
public:
    map<int, int> a;
    vector<int> twoSum(vector<int>& nums, int target) {
        int n = nums.size();
        vector<int> ans;
        for (int i = 0; i < n; ++i) {
            int v = target - nums[i];
            if (a.count(v)) {
                ans = {i, a[v]};
                break;
            }
            a[nums[i]] = i;
        }
        return ans;
    }
};

And then paste your test case into code/input.txt.

[2,7,11,15]

[3,2,4]
6
[3,3]

Run python main.py and code/output.cpp will be generated.

#include "template/template.h"
class Solution {
 public:
  map<int, int> a;
  vector<int> twoSum(vector<int>& nums, int target) {
    int n = nums.size();
    vector<int> ans;
    for (int i = 0; i < n; ++i) {
      int v = target - nums[i];
      if (a.count(v)) {
        ans = {i, a[v]};
        break;
      }
      a[nums[i]] = i;
    }
    return ans;
  }
};
Solution* solution;
Timer timer;
int main() {
  timer.start();
  solution = new Solution();
  vector<int> var1{2, 7, 11, 15};
  int var2{9};
  print(solution->twoSum(var1, var2));
  delete solution;
  print("Runtime: " + to_string(timer.end()) + " ms");

  timer.start();
  solution = new Solution();
  vector<int> var3{3, 2, 4};
  int var4{6};
  print(solution->twoSum(var3, var4));
  delete solution;
  print("Runtime: " + to_string(timer.end()) + " ms");

  timer.start();
  solution = new Solution();
  vector<int> var5{3, 3};
  int var6{6};
  print(solution->twoSum(var5, var6));
  delete solution;
  print("Runtime: " + to_string(timer.end()) + " ms");
}

Build and run code/output.cpp, and you will get following output:

[1, 0]
Runtime: 0 ms
[2, 1]
Runtime: 0 ms
[1, 0]
Runtime: 0 ms

Correct!
