#### >  make a flask app with a /hello endpoint that returns hello world  

Ok, here are the changes:

```python
app.py
<<<<<<< ORIGINAL
=======
from flask import Flask

app = Flask(__name__)

@app.route('/hello')
def hello():
    return 'Hello, World!'
>>>>>>> UPDATED
```

This code creates a Flask app and adds a `/hello` endpoint that returns "Hello, World!" when accessed.

#### >  add an endpoint like /add/3/5 which returns the sum of the 2 numbers  

Ok, here are the changes:

```python
app.py
<<<<<<< ORIGINAL
=======
from flask import Flask

app = Flask(__name__)

@app.route('/hello')
def hello():
    return 'Hello, World!'

@app.route('/add/<int:a>/<int:b>')
def add(a, b):
    return str(a + b)
>>>>>>> UPDATED
```

This code adds a `/add/<int:a>/<int:b>` endpoint that takes two integers as parameters and returns their sum when accessed.

#### >  add /fibonacci/X  

Sure, here are the changes:

```python
app.py
<<<<<<< ORIGINAL
=======
from flask import Flask

app = Flask(__name__)

@app.route('/hello')
def hello():
    return 'Hello, World!'

@app.route('/add/<int:a>/<int:b>')
def add(a, b):
    return str(a + b)

@app.route('/fibonacci/<int:n>')
def fibonacci(n):
    if n <= 0:
        return "Invalid input"
    elif n == 1:
        return "0"
    elif n == 2:
        return "0, 1"
    else:
        fib = [0, 1]
        for i in range(2, n):
            fib.append(fib[i-1] + fib[i-2])
        return ', '.join(str(x) for x in fib)
>>>>>>> UPDATED
```

This code adds a `/fibonacci/<int:n>` endpoint that takes an integer `n` as parameter and returns the first `n` numbers of the Fibonacci sequence when accessed. If `n` is less than or equal to 0, it returns "Invalid input". If `n` is 1, it returns "0". If `n` is 2, it returns "0, 1".

#### >  remove the hello endpoint  

Ok, here are the changes:

```python
app.py
<<<<<<< ORIGINAL
from flask import Flask

app = Flask(__name__)

@app.route('/add/<int:a>/<int:b>')
def add(a, b):
    return str(a + b)

@app.route('/fibonacci/<int:n>')
def fibonacci(n):
    if n <= 0:
        return "Invalid input"
    elif n == 1:
        return "0"
    elif n == 2:
        return "0, 1"
    else:
        fib = [0, 1]
        for i in range(2, n):
            fib.append(fib[i-1] + fib[i-2])
        return ', '.join(str(x) for x in fib)

def fibonacci(n):
    if n <= 0:
        return "Invalid input"

        return "0"
    elif n == 2:
        return "0, 1"
    else:
        fib = [0, 1]
        for i in range(2, n):
            fib.append(fib[i-1] + fib[i-2])
        return ', '.join(str(x) for x in fib)
```

This code removes the `/hello` endpoint from the Flask app.
