Find the sum of the integers between 100 and 200 that are
(i) divisible by 9.
(ii) not divisible by 9.

Explanation

To solve the problem, we will break it down into two parts:

### Part (i): Find the sum of integers between 100 and 200 that are divisible by 9.

1. **Identify the first multiple of 9 greater than 100**:
- The first multiple of 9 after 100 is 108 (since \(9 \times 12 = 108\)).

2. **Identify the last multiple of 9 less than 200**:
