# Operations on lists

Just like we could add two strings together or multiply a string by a number, we can do those operations for lists as well. We can add two lists together, which will result in a concatenation of the two. We can multiply a list by an integer

`n`

, which will repeat the list `n`

times.```
l1 = [1, 'abc']
l2 = [2, 'def']
print(l1 + l2) # [1, 'abc', 2, 'def']
print(l1 * 5) # [1, 'abc', 1, 'abc', 1, 'abc', 1, 'abc', 1, 'abc']
```

We can even modify the list in place with

`+=`

:```
l1 = [1, 'abc']
l2 = [2, 'def']
l1 += l2
print(l1) # [1, 'abc', 2, 'def']
print(l2) # [2, 'def']
```

To initialize a list of numbers with size

`n`

, we can simply multiply `[0]`

by `n`

:```
n = 10
l = [0] * n
print(l) # [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
l[1] = 7
print(l) # [0, 7, 0, 0, 0, 0, 0, 0, 0, 0]
```

Challenge

Given two integers

`x`

and `n`

, your task is to define an array of `n`

elements filled with `x`

as an initial value and print it.Input | Output |

10
2 | [10, 10] |

7
3 | [7, 7, 7] |
