## Treasure Map

# Instructions

You are going to write a program which will mark a spot with an X.

In the starting code, you will find a variable called ```map```.

This ```map``` contains a nested list.

When ```map``` is printed this is what the nested list looks like:

```

['⬜️', '⬜️', '⬜️'],['⬜️', '⬜️', '⬜️'],['⬜️', '⬜️', '⬜️']

```

In the starting code, we have used new lines (```\n```) to format the three rows into a square, like this:

```

['⬜️', '⬜️', '⬜️']

['⬜️', '⬜️', '⬜️']

['⬜️', '⬜️', '⬜️']

```

This is to try and simulate the coordinates on a real map.

Your job is to write a program that allows you to mark a square on the map using a two-digit system. The first digit is the vertical column number and the second digit is the horizontal row number. e.g.:

First your program must take the user input and convert it to a usable format. 

Next, you need to use it to update your nested list with an "x". 

# Example Input 1

column 2, row 3 would be entered as:

```

23

```

# Example Output 1

```

['⬜️', '⬜️', '⬜️']

['⬜️', '⬜️', '⬜️']

['⬜️', 'X', '⬜️']

```

# Example Input 2

column 3, row 1 would be entered as:

```

31

```

# Example Output 2

```

['⬜️', '⬜️', 'X']

['⬜️', '⬜️', '⬜️']

['⬜️', '⬜️', '⬜️']

```

e.g. When you hit **run**, this is what should happen:

# Hint

1. Remember that Lists start at index 0!

2. ```map``` is just a variable that contains a nested list. It's not related to the map function in Python.
