Given an integer n, add a dot (".") as the thousands separator and return it in string format.
Example 1:
Input: n = 987
Output: "987"
Example 2:
Input: n = 1234
Output: "1.234"
Constraints:
-
0 <= n <= 231 - 1
SOLUTION:
class Solution:
def thousandSeparator(self, n: int) -> str:
n = str(n)
l = len(n)
for i in range(1, l):
if i % 3 == 0:
n = n[ : l - i] + '.' + n[l - i : ]
return n
