| Statement | Operations | Iterations | Sub-Total (Operations x iterations) |
|---|---|---|---|
| 1 | 2 | 1 | 2 * 1 = 2 |
| 2a | 1 | 1 | 1 * 1 = 1 |
| 2b | 1 | n | 1 * n = n |
| 2c | 2 | n - 1 | 2 * (n - 1) = 2n - 2 |
| 3 | 3 | n - 1 | 3 * (n - 1) = 3n - 3 |
| 4 | 1 | 1 | 1 * 1 |
| $Complexity = 2 + 1 + n + 2n - 2 + 3n - 3 + 1 = 6n - 1$ |
