Longest set of Palindrome Numbers from the range [ L , R ] with at most K difference between its maximum and minimum | Function to find the maximum size of group of palindrome numbers having difference between maximum and minimum element at most K.
Stores the all the palindromic numbers in the range [ L , R ].
Traverse over the range [ L , R ].
If i is a palindrome.
Append the number in the list.
Stores count of maximum palindromic numbers.
Iterate each element in the list.
Calculate rightmost index in the list < current element + K.
Check if there is rightmost index from the current index.
Return the count.
Function to search the rightmost index of given number.
Store the rightmost index.
Calculate the mid.
If given number <= num.
Assign ans = mid.
Update low.
Update high.
return ans.
Function to check if the given number is palindrome or not.
Generate reverse of the given number.
If n is a palindrome.
