Write programs with loops that compute:
a. The sum of all even numbers between 2 and n (inclusive).
b. The sum of all squares between 1 and n (inclusive).
c. All powers of 2 from 2^theta up to 2^(n+2theta).
d. The sum of all odd numbers between a and b (inclusive), where a and b are inputs.
e. The sum of all odd digits of an input. (For example, if the input is 32677, the sum would be 3+7+7=17.) in Python.
