Adding one to the number represented as array of digits

Adding one to the number represented as array of digits is a DSA topic. In plain words you use it for a short Adding one to the number represented as array of digits example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Adding one to the number represented as array of digits example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Adding one to the number represented as array of digits.

From the example next to this theory: Adding one to the number represented as array of digits — arrays give O(1) index access; matrices are arrays of arrays.

Trap: only saying “Adding one to the number represented as array of digits” with no example. Fix that before you talk about advanced DSA.

Viva: what is Adding one to the number represented as array of digits? Then show the smallest Adding one to the number represented as array of digits example you can type. Then name the trap.

Exam tip

What is Adding one to the number represented as array of digits? Show this: the smallest Adding one to the number represented as array of digits example you can type. Trap: only saying “Adding one to the number represented as array of digits” with no example.

Example

arr = [10, 20, 30, 40]
print(arr[2], arr[-1])
matrix = [[1, 2], [3, 4]]
print(matrix[1][0])  # 3

Adding one to the number represented as array of digits — arrays give O(1) index access; matrices are arrays of arrays.
