1. Longest Palindromic Substring

Asked in companies
Given a string ’S’ consisting of lower case English letters, you are supposed to return the longest palindromic substring of ‘S’.
Note that in case of more than one longest palindromic substrings with the same length you need to return the rightmost substring in the given string. For example in string “bbbab”, there are two possible longest palindromic substrings i.e. “bbb” and “bab”, and since you are supposed to return the rightmost substring, so you need to return “bab” as the answer.
Note:
A substring is a contiguous sequence of elements within a string (for example, “bcd” is a substring of “abcde” while “bce” is not).
A string is said to be palindrome if the reverse of the string is the same as the actual string. For example, “abba” is a palindrome, but “abbc” is not a palindrome.

1. Special Sum of Array
Easy
15m average time
80% success
0/40
Asked in companies
You have been given an array/list ‘arr’ of length ‘N’, which contains single digit elements at every index. Your task is to return the sum of all elements of the array. But the final sum should also be a single digit.
To keep the output single digit - you need to keep adding the digits of the output number till a single digit is left.
For example:
For the given array [5, 8, 4, 9]
The sum of the elements of the array will be
5 + 8 + 4 + 9 = 26.
Since 26 is not a single-digit number, we will again take the sum of the digits of 26.
2 + 6 = 8.
Now 8 is a single-digit number. So we will stop here and return 8.
