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 way 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 all anagrams of a string in a larger string?

Accepted Answer

You can use a sliding window approach. Maintain a frequency map of the characters in the pattern string. Then, slide a window of the same size over the larger string, and for each window, check if the character frequencies match the pattern's frequency map.
