Practice

Problem 1: warm-up

Write a function leap that determines whether a given year is a normal year or a leap year.

Leap years occur mostly every 4 years, but every 100 years we skip a leap year unless the year is divisible by 400.

False

Next, write a function leap_years that tells you which years out of the next n years are going to be leap years.

Problem 2: advanced

Write a function which implements Pascal’s triangle.

[1, 1]
[1, 2, 1]
[1, 3, 3, 1]
[1, 4, 6, 4, 1]
[1, 5, 10, 10, 5, 1]
[1, 6, 15, 20, 15, 6, 1]





[1, 6, 15, 20, 15, 6, 1]
