I solved three questions on three different topics ( SQL, REST API, Problem Solving). The problems were basic. I had fun solving them, and feel free to share them here. Put them in good use. Cheers 🥂

## SQL: The Perfect Arrangement

```sql

SELECT ID, FIRST_NAME, LAST_NAME

FROM CUSTOMERS

WHERE LENGTH(CONCAT(FIRST_NAME, LAST_NAME)) < 12

ORDER BY LENGTH(CONCAT(FIRST_NAME, LAST_NAME)), CONCAT(FIRST_NAME, LAST_NAME), ID;

```

## Problem Solving: Conference Schedule

```python

def maxPresentations(scheduleStart, scheduleEnd):

    # Combine start and end times into tuples for easier sorting

    presentations = [(start, end) for start, end in zip(scheduleStart, scheduleEnd)]

    presentations.sort(key=lambda x: x[1])

    

    max_presentations = 0

    current_end_time = 0

    

    for start, end in presentations:

        # If the current presentation starts after the previous one ends, attend it

        if start >= current_end_time:

            max_presentations += 1

            current_end_time = end

    

    return max_presentations

```

## REST API: Patient's Medical Record

```python

import requests

def getAverageTemperatureForUser(userId):

    base_url = "https://jsonmock.hackerrank.com/api/medical_records"

    page = 1

    total_temps = 0

    total_records = 0

    while True:

        response = requests.get(f"{base_url}?userId={userId}&page={page}").json()

        data = response["data"]

        if not data:

            break

        for record in data:

            body_temperature = record.get("vitals", {}).get("bodyTemperature", 0)

            total_temps += body_temperature

            total_records += 1

        if page >= response["total_pages"]:

            break

        page += 1

    if total_records == 0:

        return "0"

    average_temp = round(total_temps / total_records, 1)

    return str(average_temp)

```
