Solution
Here is a Python solution for the problem:
def isPalindrome(n):
return str(n) == str(n)[::-1]
def findNext(n):
while not isPalindrome(n):
n += 1
return n
# Test cases
print(findNext(130)) #

A positive integer is called a palindrome if its representation in the decimal system is the same when read from left to right and from right to left. For a given positive integer K of not more than 1000000 digits, write the value of the smallest palindrome larger than K to output. Numbers are always displayed without leading zeros.InputThe first line contains integer t, the number of test cases. Followed by t lines containing integers K.OutputFor each K, output the smallest palindrome larger than K.ExampleInput:28082133Output:8182222Warning: large Input/Output data, be careful with certain languages
