Read the dialogue between a senior and a junior programmer:   Senior Programmer (Sarah): Hey, Mark! Can we talk for a moment? I noticed there's a problem with the algorithm you implemented for determining the closest taxis to our clients. Clients are getting assigned to taxis that are nowhere near their location. Junior Programmer (Mark): Oh, hey Sarah. I must have messed up. I apologize for that. [Scratching his head.] Sarah: We need to fix it as soon as possible to provide better service. In our case, we need to assign clients to the nearest taxis accurately. Junior Programmer (Mark): That’s exactly what I did: implemented measuring the distance between points and selecting the closest ones. The service then assigns the client to the closest available taxi. There may be some bug… I'll make sure to dive deeper into it and fix the issues. After all, it is a standard algorithm that all taxi and delivery services use. Senior Programmer (Sarah): It is what I think? Junior Programmer (Mark): I am dead sure.   Question: What algorithm do both the senior and junior programmers mean?

• Put the lines in the dialogue between a processor supplier and a smartphone manufacturer in a chronological order, separate the numbers with 1 gap.   Supplier: We regret any inconvenience caused, but currently, our stock of 6-nm micro-chips has been depleted. However, we do have an alternative option available. We can offer you 2000 microchips sized 12 nanometers (nm) at half the regular price. Supplier: Greetings, you have reached Winder-Chip Supply Company. How may we be of assistance today? Supplier: Of course! Our specialization lies in providing micro-chips for various electronic devices. How many microchips are you looking to order? Producer: Hi there, this is SmartTech, a smartphone production company. I'm calling to inquire about placing an order for some micro-chips. Producer: Thank you for the offer, but we specifically necessitate 6-nm microchips for our smartphones. The 6-nm chips offer us improved performance and power efficiency, aligning with our product's specifications and requirements. Therefore, we cannot consider the 12-nm chips as a suitable substitute. Producer: We are interested in purchasing 1000 micro-chips sized 6 nanometers (nm). Do you have them available in your inventory? Supplier: You're welcome! Have a splendid day as well, and we will stay in touch soon. Goodbye. Producer: We acknowledge your efforts, but presently, we cannot compromise on the quality and performance of our smartphones. We will wait until the 6-nm microchips become available. Please notify us promptly once they are back in stock, and we will proceed with our order. Supplier: Certainly, we highly value your business and comprehend your specific requirement for the micro-chips. We will prioritize restocking the 6-nm chips and promptly inform you once they are obtainable. Thank you for considering Microchip Supply Company, and we eagerly anticipate serving you in the future. Supplier: We understand your concerns. Unfortunately, due to the high demand for 6-nm micro-chips, our inventory has been depleted. We are actively working to replenish them, but it might take some time. Is there any flexibility in your requirements, or can we assist you with alternative products or services?

• Read the following monologue of an employee from a Russian scientific research institute and answer a related question. Use one word.   Our research institute has been dedicated to advancing X-ray lithography, a groundbreaking technology that deviates from traditional laser-based approaches. In the traditional laser-based method, laser beams are projected onto a semiconductor material through predefined structures containing circuit patterns. These structures, however, are expensive and time-consuming to create for each circuit design iteration.   In contrast, our X-ray technology offers a more flexible and efficient alternative. Instead of relying on predefined structures, we directly project X-ray beams onto the semiconductor material, enabling precise modification of circuit patterns. This eliminates the need for costly and time-consuming fabrication steps, facilitating rapid prototyping and customization of integrated circuits.   One notable advantage of X-ray technology is its enhanced resolution capabilities compared to traditional laser methods. The X-ray beams achieve finer feature sizes, allowing for the production of complex circuit designs. This leads to improved performance and functionality of the integrated circuits we develop.   Question: What predefined structures does this technology not require?
