Hi

I'd like to write a blog about leetcode solutions in c++. How can I evaluate those c++ code snippet using org babel?

* Array

** Two Sum

Given an array of integers, return indices of the two numbers such that they add up to a specific target.

You may assume that each input would have exactly one solution, and you may not use the same element twice.

Example:
Given nums = [2, 7, 11, 15], target = 9,

Because nums[0] + nums[1] = 2 + 7 = 9,
return [0, 1].


#+BEGIN_SRC cpp
class Solution {
public:
    vector<int> twoSum(vector<int>& nums, int target) {

    }
};
#+END_SRC

#+RESULTS:


I need to add default headers and pass arguments to the entry class.
