2597\. The Number of Beautiful Subsets

Medium

You are given an array nums of positive integers and a positive integer k.

A subset of nums is beautiful if it does not contain two integers with an absolute difference equal to k.

Return the number of non-empty beautiful subsets of the array nums.

A subset of nums is an array that can be obtained by deleting some (possibly none) elements from nums. Two subsets are different if and only if the chosen indices to delete are different.

**Example 1:**

- **Input:** nums = [2,4,6], k = 2
- **Output:** 4
- **Explanation:** The beautiful subsets of the array nums are: [2], [4], [6], [2, 6].

  It can be proved that there are only 4 beautiful subsets in the array [2,4,6].

**Example 2:**

- **Input:** nums = [1], k = 1
- **Output:** 1
- **Explanation:** The beautiful subset of the array nums is [1].

  It can be proved that there is only 1 beautiful subset in the array [1].

**Example 3:**

- **Input:** nums = [4,2,5,9,10,3], k = 1
- **Output:** 23

**Constraints:**

- <code>1 <= nums.length <= 20</code>
- <code>1 <= nums[i], k <= 1000</code>


**Solution:**

```
class Solution {

    /**
     * @param Integer[] $nums
     * @param Integer $k
     * @return Integer
     */
    function beautifulSubsets($nums, $k) {
        $countBeautifulSubsets = -1;
        $countNums = array_fill(0, 1010, 0);
        $size = count($nums);
        $dfs = function($index) use (&$dfs, &$countBeautifulSubsets, &$nums, &$countNums, $size, $k) {
            if ($index >= $size) {
                ++$countBeautifulSubsets;
                return;
            }
            $dfs($index + 1);
            $isBeautifulIncrement = $nums[$index] + $k >= 1010 || $countNums[$nums[$index] + $k] == 0;
            $isBeautifulDecrement = $nums[$index] - $k < 0 || $countNums[$nums[$index] - $k] == 0;
            if ($isBeautifulIncrement && $isBeautifulDecrement) {
                ++$countNums[$nums[$index]];
                $dfs($index + 1);
                --$countNums[$nums[$index]];
            }
        };

        $dfs(0);
        return $countBeautifulSubsets;
    }
}
```

From the [ollama help discord](https://discord.com/invite/ollama) channel:

> Docker compose: How do you pull a model automatically with container creation?

The conundrum of containerizing Ollama is that it must be running to pull a model. If you run ollama using `docker compose`, it doesn't provide a way to pull a model from the ollama registry. What's a budding generative AI nerd to do?

The answer is more `docker compose`, as in `docker compose exec`, which runs a script to download a model. Add both commands to a startup script, and you have [autollama](https://github.com/spara/autollama).

```bash
docker compose up -d
sleep 5
docker compose exec autollama sh /root/.ollama/pull_model.sh
```

Tricky Golang interview questions - Part 2: BigO of len(...)
Tags: go, interview, tutorial, programming
Published: 2024-05-23 16:50:48

An example I want to discuss is quite simple and requires knowledge about how some data types are constructed under the hood.

**Question: What is the time complexity of `len(...)` for each data type**
```go
package main

import (
	"fmt"
)

func main() {
	_ = len("string")
	_ = len([]int{1, 2, 3})
	_ = len(map[string]int{"one": 1, "two": 2, "three": 3})
}
```

The answer to this question is very easy: 
**The time complexity of the `len(...)` for all cases is O(1).**

If you answer like this, the interviewer will come up with the following question: **why?** To answer this question, we need to look under the hood of each of the types.

### String
According to the Go documentation string type can be represented as a struct, a **StringHeader**. StringHeader is the runtime representation of a string.
```go
type StringHeader struct {
	Data uintptr
	Len  int
}
```
- `Data` is a pointer, which points to an underlying (backing) byte array that stores the string data
- `Len` is the length of an underlying (backing) byte array

### Slice
Slice can also be represented as a struct, a **SliceHeader**. SliceHeader is the runtime representation of a slice.
```go
type SliceHeader struct {
    Data uintptr
    Len  int
    Cap  int
}
```
- `Data` is a pointer, which points to an underlying (backing) byte array that stores the string data
- `Len` is the length of an underlying (backing) byte array
- `Cap` is the capacity of the slice.

### Map
Map is a bit more complex data structure and is represented as a [package](https://go.dev/src/runtime/map.go) in Go. In this package, we can find the map header struct with its corresponding fields.
```go
type hmap struct {
	count      int
	flags      uint8
	B          uint8
	noverflow  uint16
	hash0      uint32
	buckets    unsafe.Pointer
	oldbuckets unsafe.Pointer
	nevacuate  uintptr
	extra      *mapextra
}
```
We need the `count` field for this struct. According to the comments
- `count` is live cells == size of map or simply length of map

Now we know how these data structures are constructed under the hood we can answer the follow-up question by the interviewer: 
**Why len(...) operations are O(1)?**
___
The `Len` function simply returns the value of the field in the header responsible for storing the length.
___
It's that easy!

Arcanium.art v1.0 Launch
Tags: ai, webdev, beta, javascript
Published: 2024-05-23 16:08:47

After what felt like an eternity in Beta, I'm thrilled to roll out [Arcanium.art](https://arcanium.art/) version 1.0 to the masses. It's been a rollercoaster of bugs, eureka moments, and a fair share of coffee-fueled late nights. But now, it's ready for prime time!

For those out of the loop—and let's be honest, that’s probably most of you—Arcanium is a Stable Diffusion art generator that prides itself on a slick user experience and foolproof simplicity. It survived a grueling six months in Alpha, where I juggled user feedback, tackled bugs, occasionally threw my hands up in frustration, took some sanity breaks, and then dove back in. Just your typical startup drama.

The loudest piece of feedback was clear: “Let me dip my toes in before I dive into the premium pool!” So, I’ve tweaked a few knobs and buttons to make that happen:

- Enjoy 5 free credits refreshed daily to get your art fix.
- Enter our Community Showcase competition to snag 250 credits—on the house.
- Our new Discord Bot is playing cop, keeping the showcase entries clean and the art generation orderly.
- We've spruced up the app to feel more like, well, an app, and less like a secret society.
- Choose between flaunting your creations publicly or keeping them under wraps.
- Upgraded models and sharper, more curated LoRA’s.
- Keep Plus membership is a steal at just $9 for unlimited access.

As always, I’m here, learning on the fly and tweaking as we go. Is a product ever really finished, or just less beta?
