So i was solving this question leetcode
link to LC

I gave a solution of O(m+n)
but that gave me time limit exceeded error.
So to check if my logic was correct or not i jumped to the local editor.
and run the code.
To my surprise it showed my a blank console.

and i stuck in a infinite loop?

#include<vector>
#include<iostream>
using namespace std;
class Solution {
public:
    vector<int> result;

    void Calc(vector<int>& BgArr, vector<int>& SmArr) {
        bool streak = false;
        
        cout<<"your inside the function";
        cout<<"about to enter loop";
        auto BgIt = BgArr.begin(), SmIt = SmArr.begin();
        while (BgIt != BgArr.end() && SmIt != SmArr.end()) {
            if (*BgIt == *SmIt && streak==false) {
          result.push_back(*BgIt);
          SmIt++;
          BgIt++;
          streak=true;
            }else if(*BgIt != *SmIt){
                if(streak==true){
                    cout<<"exited  function inside loop";
                    return;
                }
                BgIt++;
            }
        }
        
        cout<<"exited  function outside loop";
        return;
    }

    vector<int> intersect(vector<int>& nums1, vector<int>& nums2) {
        if (nums1.size() > nums2.size()) {
            Calc(nums1, nums2);
        } else {
            Calc(nums2, nums1);
        }
  return result;
    }
};




int main(){
    vector<int> arr1={1,2,2,1} ;
    vector <int> arr2={2,2};
    Solution obj1;
    
    vector<int> res=obj1.intersect(arr1,arr2);
    
    for(auto i:res){
      cout<<i;
    }
    
    return 0;
}
