Palindrome number of the positive and negative sequence is the same number, so we put this number of high-low-level exchange, that is, 1234->4321, and then use the new number to compare with the previous digital exchange is equal, that is, can determine whether this number is a palindrome number. Note : Negative numbers are not palindrome numbers.

Consider a string s that contains only the lowercase Latin alphabet. We define the "out" of a substring t of sThe present value is the number of occurrences of T in s multiplied by the length of T. Please find out the most in all palindrome strings of SLarge occurrence value. String length ≤300000

Determine if a number is a palindrome and try to use no additional space. Note: Can negative numbers also become palindrome numbers? If you want int to be a string, be careful not to use other space for this constraint. You can also flip an int, but it is possible to overflow.1 Public classSolution {2 Public BooleanIspalindrome (intx) {3 if(xreturn false;4 5 inttemp = x, Reversex = 0;

Give a number, well, it's not a number, it's a bunch of numbers,
Like 98237482340328490328490324893024, a very long number.
To find the next palindrome, this palindrome is larger than the current value (not equal to).
Such as:
9 9 9 9->1 0 0 0 1
1 2 3 4 5->1 2 4 2 1
