Question 1

How do you check if a string is a palindrome?

Accepted Answer

You can check if a string is a palindrome by comparing the string with its reverse. Another common method is to use two pointers, one at the beginning and one at the end, and check if the characters are the same as you move towards the center.

Question 2

How do you find the first non-repeated character in a string?

Accepted Answer

A common approach is to use a hash map or a frequency array to store the count of each character. Then, iterate through the string again and return the first character with a count of one.
