DAY 52 OF 90 · Loops inside loops

Times table

Medium90 Days of Looping

Inputs

n is a whole number from 0 to 8.

Your tasks

Create an empty list table.
Use an outer loop for each row number r from 1 up to and including n. In it, build a list row with an inner loop for each column number c from 1 up to and including n, adding r * c.
Add row to table after the inner loop ends.
Complete timesTable so it returns table. Return it, do not print it.

Example

With n = 3, timesTable returns [[1, 2, 3], [2, 4, 6], [3, 6, 9]].

Rules

If n is 0, return an empty list.

Test data

TEST DATA 1: n is 3

TEST DATA 2: n is 0

Practice focus

Nested loops compare every pair and build rows. The slow, simple answer to most problems is two loops. Knowing it is what lets you see how to beat it.
