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+ ...

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...
