How can I optimize the BinaryTree implementation for balanced insertions and efficient lookups?
I’m working on a binary tree implementation in Java and need to ensure it performs optimally for both insertions and lookups. Currently, the implementation is a basic binary search tree (BST) and does not guarantee balanced insertions, which can lead to degraded performance in the worst case.
What are the common methods to find the second largest element in an array, and what is the time complexity of each method?
static int secondLargest(int n,int arr[]){ int max=0,secondmax=-1; for(int i=0;i<n;i++){ if(arr[i]>max){ max=arr[i]; } } for(int i=0;i<n;i++){ if(arr[i]<max && arr[i]>secondmax){ secondmax=arr[i]; } } return secondmax; // Arrays.sort(arr); // for(int i=1;i<n;i++){ // if(arr[n-i]!=arr[n-i-1]){ // return arr[n-i-1]; // } // } // return -1; } } Inputs Can be following 6 12 35 1 10 34 1 or 10 […]
Balancing a Binary Search Tree After Multiple Insertions
After inserting multiple elements into a binary search tree (BST), the tree becomes unbalanced and its height increases, leading to inefficient operations. I need to implement a method to balance the BST to ensure that it maintains efficient operations.

Understanding Differences in Output Using HashSet vs ArrayList for Storing Square Numbers
When I use the following code snippet with a HashSet to store square_nums, the output is 5 for n=23. Normally, it should produce the same output as the code below, which outputs 4. What am I missing?
Explain how cache performance can influence the efficiency of following bubble sort
Need to explore the difference comparatively normal bubble sort method and efficient bubble sort method.
How can I convert Stack to int[] in Java?
I have a Stack<Integer> and need to output as int[].
What would be a good way to do so in Java?
Task management java project
So I have to do a task management system project in java and show the best data structure to use and why? So I’m thinking of using Array and Linked list so how do I compare these two by coding?
Should I do two different codes two see the time/space it takes or should I use the same coding?
If you have other suggestions, I’ll love to take.
