Transcribed Image Text:**Requirements:**
- **User Interface (UI):** Must have a button (for graphical UIs) or be able to receive a user command (for text-based UIs).
- **Processes:** Each of the three programs must run in a separate process.
- **Program Independence:** Programs must not call each other directly; they should not import one program into another.
- **Communication via Text Files:**
1. **UI Interaction:**
- The UI initiates the pseudo-random number generation by writing "run" to a file named `prng-service.txt`.
2. **PRNG Service:**
- Reads from `prng-service.txt`, deletes its content, and writes a pseudo-random number into it.
3. **UI Retrieval:**
- The UI reads this pseudo-random number from `prng-service.txt`.
4. **Image Service Interaction:**
- The UI writes the pseudo-random number into `image-service.txt`.
5. **Image Service:**
- Reads, erases `image-service.txt`, and writes the path of an image into it.
6. **UI Display:**
- The UI reads the image path from `image-service.txt` and displays the respective image to the user.
- **Demonstration:** Create a short video (5 minutes or less) showcasing how these requirements are met.

Transcribed Image Text:**Overview**
To demonstrate your ability to implement the microservices architecture, write software comprised of three separate programs:
1. **PRNG Service**: A program that generates pseudo-random numbers.
2. **Image Service**: A program that, given a non-negative integer \(i\), returns the \(i^{th}\) image in a set (order doesn’t matter).
- If \(i\) is greater than or equal to the number of images, use \(i\) modulo the size of the image set.
3. **User Interface (UI)**: A user interface that either has a button or can receive a user command. When the button is pushed or the command is entered:
- (a) UI calls the PRNG Service
- (b) UI calls the Image Service using the pseudo-random number from the PRNG Service
- (c) UI displays the image (or a path to it)
Programs can be written in **any language(s)**.
**Use any set of images** (e.g., downloaded from [Kaggle](https://www.kaggle.com/)). Store images locally in a folder; no API calls needed. No database needed.
**Requirements**
- UI must either have a button (if UI is graphical) or be able to receive a user command (if UI is text-based).
- Each of the three programs must run in a **different process**.
- Programs must **NOT call each other directly** (e.g., do not import one program into another).
- As the communication pipe, use text files as follows:
1. UI calls PRNG Service by writing the word "run" to `prng-service.txt`.
