The count-and-say sequence is the sequence of integers with the first five terms as following:

1. 1 2. 11 3. 21 4. 1211 5. 111221

`1`

is read off as `"one 1"`

or `11`

.

`11`

is read off as `"two 1s"`

or `21`

.

`21`

is read off as `"one 2`

, then `one 1"`

or `1211`

.

Given an integer *n*, generate the *n*^{th} term of the count-and-say sequence.
