Merge k sorted arrays into a single sorted array efficiently.
Use a min-heap to efficiently get the smallest element from the k arrays.
Initialize the heap with the first element of each array.
Extract the minimum element from the heap, and add the next element from the same array to the heap.
Repeat until all elements from all arrays are processed.
Time complexity is O(N log k), where N is the total number of elements...
Implementing a rate limiter using a sliding window algorithm to control request rates efficiently.
A sliding window allows tracking requests over a specified time frame.
It divides time into fixed intervals (e.g., 1 minute) and counts requests in the current interval.
When a request comes in, check if the count exceeds the limit; if yes, deny the request.
Example: Allow 100 requests per minute; if 101st request comes ...
Spiral traversal of a matrix involves visiting elements in a spiral order, starting from the top-left corner.
Start from the top-left corner of the matrix.
Traverse the first row from left to right.
Traverse the last column from top to bottom.
Traverse the last row from right to left (if there are remaining rows).
Traverse the first column from bottom to top (if there are remaining columns).
Repeat the process for the i...
Validate an IP address to determine if it's a valid IPv4 or IPv6 format.
IPv4 consists of four octets (0-255) separated by dots. Example: 192.168.1.1
IPv6 is represented as eight groups of four hexadecimal digits separated by colons. Example: 2001:0db8:85a3:0000:0000:8a2e:0370:7334
Check for leading zeros in IPv4 octets (e.g., 192.168.01.1 is invalid).
Ensure IPv6 addresses do not exceed 128 bits and are properly form...
Formatting a URL involves structuring it correctly for web access, ensuring it adheres to standards and is user-friendly.
Use 'https://' for secure connections. Example: 'https://www.example.com'.
Ensure proper encoding of special characters. Example: 'Hello World' becomes 'Hello%20World'.
Maintain a clear structure: scheme, host, path, and query parameters. Example: 'https://www.example.com/path?query=value'.
Avoid u...
Creating and using class instances in Python for automation testing.
Define a class using the 'class' keyword. Example: 'class MyClass:'.
Create an instance of the class by calling it. Example: 'my_instance = MyClass()'.
Access class attributes and methods using the instance. Example: 'my_instance.method_name()'.
Use '__init__' method for initializing instance variables. Example: 'def __init__(self, value): self.value...

Python functions can return multiple values using tuples, lists, or dictionaries, allowing flexibility in return types.
Python functions can return multiple values as a tuple: `def func(): return 1, 2`.
You can also return a list: `def func(): return [1, 2, 3]`.
Returning a dictionary allows named access: `def func(): return {'a': 1, 'b': 2}`.
Using `*args` and `**kwargs` allows for variable-length arguments and keywo...
Yes, a company can have positive cash flow despite reporting a net loss due to non-cash expenses and working capital changes.
