Problem of the Day

1. Write a program that contains 2 functions.

• The function distanceToOrigin(x, y) computes and returns the distance between the points (0, 0) and (x, y) in 2-dimensional space.
  
• The main() function computes and prints the distance from the origin for all points (a, b) such that a and b are integers between 1 and 3.
  

2. Write a function isEven(x) that takes an integer x and returns True if x is even and False otherwise.
