Your way of explaining and presentation is great bro. you deserve more views but small suggestion after you explain the code if you code along in leetcode it will be more easier for us to understand rather than seeing the final code so it might increase the views.

i do not plan on coding along in leetcode, there are a lot of youtubers who do the exact same thing. languages keep changing with time, so I would focus primarily on problem solving. You have so many chat GPTs available too which can write the code for you.

Sir, I wanted to see the code for stack using 2 queues😢

Did you check the code provided in the video description?

@akhileshnandanwar7443 3 ай бұрын

sir there is no code of stack using 2 queues

class StackImplUsingQueues { Queue q1 = new LinkedList(); Queue q2 = new LinkedList(); public int pop() { if (q1.peek() == null) { System.out.println("The stack is empty, nothing to return"); int i = 0; return i; } else { int pop = q1.remove(); return pop; } } public void push(int data) { if (q1.peek() == null) { q1.add(data); } else { for (int i = q1.size(); i > 0; i--) { q2.add(q1.remove()); } q1.add(data); for (int j = q2.size(); j > 0; j--) { q1.add(q2.remove()); } } }
