|
|
|
<2-3 sentences. What did you change and what is the high-level idea?

## Code (relevant snippet)
|
|
|
|
```cpp

## Analysis
|
|
|
|
<Why it worked or did not. What surprised you. What bottleneck this hits
|
|
or moves. Mention generated assembly or a profile if relevant.>
|
|
|
|
## Takeaway
|
|
|
|
<One short paragraph that could be lifted straight into the report.>
