+# [906. Super Palindromes](https://leetcode.com/problems/super-palindromes/)
+
+Let's say a positive integer is a *superpalindrome* if it is a palindrome, and it is also the square of a palindrome.
+
+Now, given two positive integers `L` and `R` (represented as strings), return the number of *superpalindromes* in the inclusive range `[L, R]`.
+
+Example 1:
+
+```text
+Input: L = "4", R = "1000"
+Output: 4
+Explanation: 4, 9, 121, and 484 are *superpalindromes*.
+Note that 676 is not a *superpalindrome*: 26 * 26 = 676, but 26 is not a palindrome.
+```
+
+Note:
+
+1. `1 <= len(L) <= 18`
+1. `1 <= len(R) <= 18`
+1. `L` and `R` are strings representing integers in the range `[1, 10^18)`.
+1. `int(L) <= int(R)`
