Minimum product of k integers in an array of positive integers

Minimum product of k integers in an array of positive integers is a DSA topic. In plain words you use it for a short Minimum product of k integers in an array of positive integers example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Minimum product of k integers in an array of positive integers example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Minimum product of k integers in an array of positive integers.

From the example next to this theory: Minimum product of k integers in an array of positive integers — arrays give O(1) index access; matrices are arrays of arrays.

Trap: only saying “Minimum product of k integers in an array of positive integers” with no example. Fix that before you talk about advanced DSA.

Viva: what is Minimum product of k integers in an array of positive integers? Then show the smallest Minimum product of k integers in an array of positive integers example you can type. Then name the trap.

Exam tip

What is Minimum product of k integers in an array of positive integers? Show this: the smallest Minimum product of k integers in an array of positive integers example you can type. Trap: only saying “Minimum product of k integers in an array of positive integers” with no example.

Example

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

Minimum product of k integers in an array of positive integers — arrays give O(1) index access; matrices are arrays of arrays.
