Hashtable is faster for finding an item than a sorted list.
Hashtable has constant time complexity O(1) for finding an item.
Sorted list has logarithmic time complexity O(log n) for finding an item.
Hashtable uses hashing to directly access the item's location.
Sorted list requires binary search to find the item's location.
Hashtable is ideal for large datasets with frequent lookups.
Sorted list is ideal for datasets that re
JSON and XML are the most popular data interchange formats when using APIs.
JSON (JavaScript Object Notation) is a lightweight format that is easy to read and write. It is widely used in web APIs.
XML (Extensible Markup Language) is a more complex format that is also widely used in web APIs.
Other formats include CSV (Comma Separated Values), YAML (YAML Ain't Markup Language), and Protocol Buffers.

Check if a number is a power of 2 and odd.
To check if a number is a power of 2, use bitwise AND operator with the number and its predecessor. If the result is 0, it is a power of 2.
To check if a number is odd, use modulus operator with 2. If the result is 1, it is odd.
Example code in Python:
def is_power_of_two(num):
return num & (num - 1) == 0
def is_odd(num):
return num % 2 == 1
