Count and Say

The count-and-say sequence starts with "1" and each subsequent term describes the previous:

Given n, return the nth term.

Input:

Output:

Reasoning:

The sequence starts with "1" as the first term.
To generate the next term, we describe the previous term: the second term is "11" because the first term has one "1".
The third term is "21" because the second term has two "1"s.
The fourth term is "1211" because the third term has one "2" and one "1", which leads to the output for the given input $n = 4$ .
