## Exercises Level III - Slicing
|
||
|
||
Discover the power of slicing.
|
||
|
||
1. **[Slice the numbers](https://github.com/inancgumus/learngo/tree/master/16-slices/exercises/13-slicing-basics)**
|

||
## Exercises Level IV - Internals
|
||
|
||

|
||
|
||
3. **[Observe the memory allocations](https://github.com/inancgumus/learngo/tree/master/16-slices/exercises/18-internals-slice-header)**
|
||
|
||
4. **[Observe the length and capacity](https://github.com/inancgumus/learngo/tree/master/16-slices/exercises/19-observe-len-cap)**
|
||
|
||
5. **[Observe the capacity growth](https://github.com/inancgumus/learngo/tree/master/16-slices/exercises/20-observe-the-cap-growth)**

## Exercises Level V - Advanced Operations
|
||
|
||
Commonly used and more advanced operations are available to slices. Now, it's time to test yourself and fix some common problems.
|
||
|
||
★ WARNING ★
|
||
Please update your local copy of the prettyslice package for some examples to work. [Please find the intructions how to do so here](../README.md).
|
||
|
||
1. **[Practice Advanced Slice Operations](https://github.com/inancgumus/learngo/tree/master/16-slices/exercises/22-adv-ops-practice)**
|
||
|
||
Let's warm you up for the advanced slice operations, and reinforce your neurons.
|
||
|
||
2. **[Limit the backing array sharing](https://github.com/inancgumus/learngo/tree/master/16-slices/exercises/23-limit-the-backing-array-sharing)**
|
||
|
||
Your API does not control the slices that it share with the outside world. You need to fix it.
|
||
|
||
3. **[Fix the Memory Leak](https://github.com/inancgumus/learngo/tree/master/16-slices/exercises/24-fix-the-memory-leak)**
|
||
|
||
A slice retrieved from an API causes a memory leak in your program. You need to fix it.
|
||
|
||
4. **[Add newlines to the lyric sentences](https://github.com/inancgumus/learngo/tree/master/16-slices/exercises/25-add-lines)**
|
||
|
||
Use the power of the `copy()` function and add newlines into a new buffer from a string slice. This exercise is more tricky than you might think.
|
||
|
||
5. **[Print Daily Requests](https://github.com/inancgumus/learngo/tree/master/16-slices/exercises/26-print-daily-requests)**
|
||
|
||
Group the requests log into a multi-dimensional from a single-dimensional slice. Allocate a slice with the exact size needed by doing some wizardary calculations. And lastly, pretty print the result.
