Level Order line wise - Zig Zag | Solution

[@jiosim1377]

Im from c++ background but for whenever i dont understand any question from the course that im doing i directly come to your lectures and the question becomes crystal clear!!!

[@md.yasirarafat4581]

you are best cs teacher .Learning from Bangladesh.

[@soumyaagrawal9045]

You make the concept quite clear to the students which increases more interest in coding and watching your upcoming videos.

[@shubhamchoubey3948]

Bhaiya, apke yaha aake lagta hai o bhai saab ab toh mai kisi aur ko v samjha sakta hu ye question 🔥

[@surajmodanwal3726]

I dont know pepcoding ka kya hua ab, but sumeet sir is one of the best teacher i ever met.

[@sasidharnaidu4507]

I was able to implement the same, but using queues 🎉

[@MrDishajain]

Hi Sir, Your solution is quite easy to understand and your way of teaching is awesome . But apke solution are not the best or optimal approach with least space or time complexity. Could you please start from brute force method and then take us to optimal solution because in interview we can not use this much of space complexity.

Then join live clasess

[@LegitGamer2345]

this is an optimal solution though

[@LegitGamer2345]

and in most of the videos sir explains optimal solution , it is up to you to come up with a brute force solution

[@mickyman753]

level 1 is for learning ,not for interview prep , try doing level 2 , there almost of the level 1 problem's most optimal approach is tackled

superb collection of videos

[@mohammednooruddin4165]

If we use main queue and child stack we get same zig zag order

Which application do you use for drawing and explaining concepts?

[@054_heenaahmed8]

openboard

[@RassiDIY]

Hello Sir. Can you share the complete code?

[@kritmol7783]

Sir is question me Queue use kyu nhi kri apne? like previous question LevelOrder Linewise me kri thi

[@em_nikhil_007]

Lo bhai aapki isksha puri kar di gyi void l_order_linewise_zigzag(Node *root){ bool f=true; queue q; stack st; q.push(root); while(q.size()>0){ cout=0;i--){ st.push(q.front()->children[i]); } } q.pop(); if(q.size()==0){ while(st.size()>0){ q.push(st.top()); st.pop(); } f=!f; cout
