Prompt
Here is a short Python program.
```python
peak = 5
cost = 8
step = 1
if step > cost:
step = peak * 2
else:
peak += step
peak += cost
cost = cost * 3
cost = peak * 2
step = peak * 3
if peak == 1:
cost = step - 1
else:
cost = cost * 3
if peak == step:
cost = cost * 2
cost = step + 9
cost = step * 2
step = cost if cost < peak else peak + 7
step -= 1
if peak > cost:
cost += step
step += 8
```
After this program runs, what is the value of `peak`? Work through it carefully, then give the final answer on its own last line as `ANSWER: <python literal>`.
Response
To find the value of `peak`, let's trace the program step-by-step:
1. **Initial values:**
`peak = 5`
`cost = 8`
`step = 1`
2. **First `if/else` block:**
`if step > cost:` (1 > 8 is False)
`else:`
`peak += step` $\rightarrow$ `peak = 5 + 1 = 6`
`peak += cost` $\rightarrow$ `peak = 6 + 8 = 14`
3. **Sequential assignments:**
`cost = cost * 3` $\rightarrow$ `cost = 8 * 3 = 24`
`cost = peak * 2` $\rightarrow$ `cost = 14 * 2 = 28`
`step = peak * 3` $\rightarrow$ `step = 14 * 3 = 42`
4. **Second `if/else` block:**
`if peak == 1:` (14 == 1 is False)
`else:`
`cost = cost * 3` $\rightarrow$ `cost = 28 * 3 = 84`
5. **Third `if` block:**
`if peak == step:` (14 == 42 is False)
(The block is skipped)
6. **Further assignments:**
`cost = step * 2` $\rightarrow$ `cost = 42 * 2 = 84`
`step = cost if cost < peak else peak + 7`
Is `cost < peak`? (84 < 14 is False)
So, `step = peak + 7` $\rightarrow$ `step = 14 + 7 = 21`
`step -= 1` $\rightarrow$ `step = 21 - 1 = 20`
7. **Final `if` block:**
`if peak > cost:` (14 > 84 is False)
(The block is skipped)
Throughout the entire execution, the variable `peak` was modified only once in the first `else` block (where it became 6 and then 14). No subsequent operations changed the value of `peak`.
Final value of `peak`: 14
