Calculate the median from a continuous stream of numbers efficiently.
Use two heaps: a max-heap for the lower half and a min-heap for the upper half.
Insert numbers into the appropriate heap based on their value.
Balance the heaps to ensure their sizes differ by at most one.
The median is the root of the max-heap if it has more elements, or the average of both roots if they are equal in size.
Example: Stream = [1, 5, 2...
Calculate the height of a tree using a segment tree data structure.
A segment tree is a binary tree used for storing intervals or segments.
Each node represents an interval and stores information about that interval.
To find the height, recursively calculate the height of left and right subtrees.
Example: For a tree with nodes 1, 2, 3, the height is 2 (root + 1 level).
Height can be defined as the number of edges in th...
Joins are required to combine data from multiple tables based on related columns.
To retrieve related data from different tables, e.g., joining 'patients' and 'appointments' tables to get patient appointment details.

To enforce referential integrity by linking primary keys in one table to ...
Sorting an array involves arranging its elements in a specific order, typically ascending or descending.
Use built-in functions: Most programming languages have built-in sort functions. Example: `array.sort()` in Python.
Custom sorting: You can define your own sorting logic using comparison functions. Example: `sorted(array, key=len)` sorts by string length.
Sorting algorithms: Implement algorithms like Quick Sort or...
Reversing a string involves rearranging its characters in the opposite order, which can be done using various methods in programming.
Using Python: str[::-1] reverses a string. Example: 'hello' becomes 'olleh'.
Using Java: Use StringBuilder's reverse() method. Example: new StringBuilder('hello').reverse().toString() results in 'olleh'.
Using JavaScript: Split the string into an array, reverse it, and join it back. Ex...

The Two Sum problem involves finding two numbers in an array that add up to a specific target sum.
Use a hash map to store numbers and their indices for quick lookup.
Iterate through the array, calculating the complement (target - current number).
Check if the complement exists in the hash map; if yes, return the indices.
Example: For nums = [2, 7, 11, 15] and target = 9, return indices [0, 1] (2 + 7 = 9).
Time complex...
