Actually I was waiting for this video. just now I solved by recursion Mik. later I will watch memoization concept thank you haha

[@souravjoshi2293]

Awesome bhai. Recursion se bhi bangaya to it's a great achievement. I am also working hard and hope to be able to solve on my own 😃

[@siddharthshinde7238]

can u make a video of solving this question using java ?

[@codestorywithMIK]

Code for memoizing using vector : class Solution { public: //unordered_map mp; vector mp; vector solve(int n) { if(n % 2 == 0) { //even return {}; } if(n == 1) { TreeNode* root = new TreeNode(0); return {root}; } if(mp[n].size() != 0) { return mp[n]; } vector result; for(int i = 1; ileft = l; root->right = r; result.push_back(root); } } } return mp[n] = result; } vector allPossibleFBT(int n) { mp.resize(21); return solve(n); } };

[@39_jatinjain4]

Why last walle 2 for loops??

[@Rajdweep]

to get all diff combos of full binary trees

[@codestorywithMIK]

Correct

[@shabananoor9423]

Made it easy ❤❤❤

[@Rajat_maurya]

not able to replace the map into vector any help for memo ??

[@codestorywithMIK]

Sure. Find the code below using vector for memoization : class Solution { public: //unordered_map mp; vector mp; vector solve(int n) { if(n % 2 == 0) { //even return {}; } if(n == 1) { TreeNode* root = new TreeNode(0); return {root}; } if(mp[n].size() != 0) { return mp[n]; } vector result; for(int i = 1; ileft = l; root->right = r; result.push_back(root); } } } return mp[n] = result; } vector allPossibleFBT(int n) { mp.resize(21); return solve(n); } };

[@Rajat_maurya]

@@codestorywithMIK done, just a question when i declare globally vector mp(21); it shows error, but when i do resize in main call then it resolves.

[@codestorywithMIK]

Actually C++ doesn’t allow that, i need to recall the reason but I will definitely share soon. Meanwhile, please read this - stackoverflow.com/questions/788703/initializing-a-vector-before-main-in-c

By any chance, do U give lc daily?

[@codestorywithMIK]

Sorry I couldn’t get it. Lc daily means ?

[@xiaoshen194]

​@@codestorywithMIKah pardon me, I meant to say weekly contest. Btw hopefully bottom up jld hi ajae, ❤ Ur content 🙃

[@codestorywithMIK]

Actually i had given some long ago. But I usually travel now during weekends to relax my mind after busy weekdays and to enjoy. But yeah, i will start giving the contests soon and also planning to cover them in my channel (hard and medium ones).

[@Rajdweep]

this was a tuff qs man very unintuitive i kept thinking how to clone tree and put seperate trees in list every time n becomes 0

[@codestorywithMIK]

No worries. That’s how we all grow 😇❤️💪
