    866 - Prime Palindrome.

    Medium

    Given an integer n, return the smallest prime palindrome greater than or equal to n.

    An integer is prime if it has exactly two divisors: 1 and itself. Note that 1 is not a prime number.

    • For example, 2, 3, 5, 7, 11, and 13 are all primes.

    An integer is a palindrome if it reads the same from left to right as it does from right to left.

    • For example, 101 and 12321 are palindromes.

    The test cases are generated so that the answer always exists and is in the range [2, 2 * 108].

    Example 1:

    Input: n = 6

    Output: 7

    Example 2:

    Input: n = 8

    Output: 11

    Example 3:

    Input: n = 13

    Output: 101
