Let's say a positive integer is a super-palindrome if it is a palindrome, and it is also the square of a palindrome.

\n\n

Given two positive integers left and right represented as strings, return the number of super-palindromes integers in the inclusive range [left, right].

\n\n

 

\n

Example 1:

\n\n
\nInput: left = "4", right = "1000"\nOutput: 4\nExplanation: 4, 9, 121, and 484 are superpalindromes.\nNote that 676 is not a superpalindrome: 26 * 26 = 676, but 26 is not a palindrome.\n
\n\n

Example 2:

\n\n
\nInput: left = "1", right = "2"\nOutput: 1\n
