Is the String a Palindrome?
AskAI
This problem asks whether a given string is a palindrome. A palindrome is a word or phrase that is the same forwards and backwards. In this case, the input string " racecar" is a palindrome, so the output would be "true".
Longest Common Prefix in an Array of Strings
AskAI
Given an array of strings, this problem seeks to find the longest common prefix. This can be done by comparing the first string in the array with the second string, then the second string with the third string, and so on. The longest common prefix is the substring that is shared by all strings in the array.
Find the length of the longest substring without repeating characters.
AskAI
This problem asks you to find the length of the longest substring in a given string without any repeating characters. Examples are provided to illustrate how this would work. Note that the answer must be a substring, not just a subsequence.
Check if a singly linked list is a palindrome.
AskAI
To check if a singly linked list is a palindrome, we can traverse the list and push the elements onto a stack. Then, we can traverse the list again and compare the elements to the elements on the stack, popping off the stack as we go. If the list is a palindrome, then the elements should match. If not, then the list is not a palindrome.
Counting Strings in an Array
AskAI
This problem asks the reader to return a map consisting of the strings in an array as keys, and the number of times each string appears in the array as values.
Largest Integer in a List
AskAI
This problem asks you to write a function that returns the largest integer in a given list. For example, if the input list is [1, 2, 3, 4, 5], the largest integer in the list is 5.
Palindrome Linked List
AskAI
This problem asks whether a given singly linked list is a palindrome. A palindrome is a word, phrase, or sequence that reads the same backward as forward. In this case, the list is a palindrome if the elements in the list read the same forward as backward.
Duplicate values in unsorted array
AskAI
This technical problem deals with finding duplicate values in an unsorted array. The function should return true if any duplicates are found.
