My leetcode practice with a unit test framework

Write leetcode code with C++11 and test them easily with full unit test features! Use Catch2 as unit-test framework

Usage

For each leetcode problem, generate source files at the src directory through command ./run.py gen "$id. $probem_title"

# ./run.py gen "$id. $probem_title"
./run.py gen "1. Two Sum"

The generated files strtucured like:

$id. $problem_title
├──  solution.hpp    # implement the solution
└──  TEST.cpp        # UNIT Testcases

Now. Write Your Code for test and solution!

/** 1. Two Sum/TEST.cpp **/
#include "../../framework/header.hpp"
#include "../../framework/common.hpp"
#include "solution.hpp"

TEST_CASE( "TC for Two Sum", "[leetcode]" ) {
    Solution s;

    vector<int> v = {1, 3, 4, 5, 6, 7, 2};
    REQUIRE( s.twoSum(v, 11) == vector<int>({2, 4}) );
}

/** 1. Two Sum/solution.hpp **/
class Solution {
public:
    vector<int> twoSum(vector<int>& nums, int target) {
        unordered_map<int, int> map;
        for(auto i = 0; i < nums.size(); ++i){
            int complement = target - nums[i];
            if(map.find(complement) == map.end())
                map[nums[i]] = i;
            else
                return {map[complement], i};
        }
        return vector<int>();
    }
};

Test it with one-line !

./run.py test 1

================================================   
  All tests passed (1 assertions in 1 test case)
