Time complexity refers to the amount of time an algorithm takes to run as a function of the input size.

• It measures how the runtime of an algorithm grows as the input size increases.

• Common time complexities include O(1) constant time, O(log n) logarithmic time, O(n) linear time, O(n^2) quadratic time, and O(2^n) exponential time.

• Understanding time complexity helps in analyzing and optimizing algorithms for efficiency.

• Ex...read more

List is mutable, tuple is immutable in Python.

• List can be modified, tuple cannot

• List uses square brackets [], tuple uses parentheses ()

• List is slower than tuple for iteration and indexing

Sort a list with duplicate numbers using Python

• Use the sorted() function to sort the list in ascending order

• To maintain the duplicate numbers, use a lambda function as the key parameter in sorted()

• Example: nums = [3, 1, 4, 1, 5, 9, 2, 6, 5], sorted_nums = sorted(nums, key=lambda x: (x, nums.index(x)))
