Memory leak is a situation where a program fails to release memory it no longer needs.
Memory leaks can cause a program to consume more and more memory over time, eventually leading to crashes or other issues.
Memory leaks can be caused by programming errors such as not freeing memory after it is no longer needed.
Tools like valgrind can be used to detect memory leaks in C and C++ programs.
Examples of memory leaks include...
Arrays have fixed size and can lead to memory wastage and performance issues.
Arrays have a fixed size and cannot be resized dynamically.
Inserting or deleting elements in an array can be time-consuming.
Arrays can lead to memory wastage if they are not fully utilized.
Arrays can cause performance issues if they are too large and need to be traversed frequently.
Arrays can also be prone to buffer overflow attacks.
Example: A...

BST stands for Binary Search Tree, a data structure used for efficient searching and sorting operations.
BST is a tree-like data structure where each node has at most two children.
The left child of a node contains a value less than the parent node, while the right child contains a value greater than the parent node.
BST allows for efficient searching and sorting operations with a time complexity of O(log n).
Examples of a...
Number of possible BSTs with 2 and 3 nodes.
For 2 nodes, only 2 BSTs are possible.
For 3 nodes, 5 BSTs are possible.
Number of BSTs can be calculated using Catalan numbers formula.
Catalan(2) = 2, Catalan(3) = 5.
Answering the question about possible trees with two and three nodes.
For two nodes, there is only one possible tree.
For three nodes, there are three possible trees.
The formula for calculating the number of possible trees with n nodes is (2n-3)!!.
The double exclamation mark represents the double factorial function.
The double factorial function is defined as n!! = n(n-2)(n-4)...(1 or 2).
B+ trees are balanced trees used for indexing and searching large amounts of data.
B+ trees are similar to binary search trees but have multiple keys per node.
They are commonly used in databases and file systems.
B+ trees have a high fanout, reducing the number of disk accesses required for searching.
They are also self-balancing, ensuring efficient performance even with large amounts of data.
Example: In a database, a B+ ...

I prefer hash tables for their constant time lookup and insertion.
Hash tables are efficient for storing and retrieving data.
They have constant time complexity for both insertion and lookup.
They can be implemented using arrays or linked lists.
Examples include Python's dictionary and Java's HashMap.
Yes, we can implement a stack using two queues.
Push operation: Enqueue the element to the first queue.
Pop operation: Dequeue all elements from the first queue and enqueue them to the second queue until the last element. Dequeue and return the last element. Swap the names of the queues.
Top operation: Same as pop operation but don't dequeue the last element.
Example: Push 1, 2, 3. Queue 1: 1 2 3. Queue 2: empty. Pop opera...

Count the number of continuous sequences with equal number of 0's and 1's in an array.
Iterate through the array and keep track of the count of 0's and 1's encountered so far.
Store the difference between the counts in a hash table and increment the count for that difference.
If the difference is already present in the hash table, add the count to the existing value.
Return the sum of all values in the hash table.
Count the number of palindromic substrings in a given string.
A substring is a contiguous sequence of characters within a string.
A palindrome is a string that reads the same backward as forward.
Use dynamic programming to count all palindromic substrings.
Time complexity can be reduced to O(n^2) using Manacher's algorithm.
Find the longest palindrome in a given string in linear time complexity.
Use Manacher's algorithm to find the longest palindrome in a string in O(n) time complexity.
The algorithm involves preprocessing the string to add special characters to handle even and odd length palindromes.
Then, it uses a combination of dynamic programming and symmetry properties to find the longest palindrome.
For example, in the string 'babad',
The value of pie is a mathematical constant approximately equal to 3.14159.
Pie is the ratio of the circumference of a circle to its diameter.
It is an irrational number, meaning it cannot be expressed as a finite decimal or fraction.
Pie is commonly used in geometry and trigonometry calculations.
The value of pie is often approximated as 3.14 or 22/7.
