Python

R4.1

Write a while loop that prints

a. All squares less than n. For example, if n is 100, print 0 1 4 9 16 25 36 49 64 81.

b. All positive numbers that are divisible by 10 and less than n. For example, if n is 100, print 10 20 30 40 50 60 70 80 90

c. All powers of two less than n. For example, if n is 100, print 1 2 4 8 16 32 64.

R4.2

Write a loop that computes

a. The sum of all even numbers between 2 and 100 (inclusive).

b. The sum of all squares between 1 and 100 (inclusive).

c. The sum of all odd numbers between a and b (inclusive).

d. The sum of all odd digits of n. (For example, if n is 32677, the sum would be 3 + 7 + 7 = 17.)
