Find index of element in sorted array
AskAI
Algorithms, Data Structures and Coding
This problem deals with finding the index of an element in a sorted array of integers. The input is a sorted array of integers and an integer value to find. The output is the index of the value in the array, or -1 if the value is not present in the array.
Stack Order Checker
AskAI
Algorithms, Data Structures and Coding
The function should return true if the stack is in sorted order (increasing order), and false otherwise.
Cycles in Undirected Graphs
AskAI
Algorithms, Data Structures and Coding
This problem is about detecting cycles in undirected graphs. Given a graph, the function should return true if there is a cycle, and false otherwise.
Sum all elements in a list
AskAI
Algorithms, Data Structures and Coding
To sum all elements in a list, we can simply iterate through the list and add each element to a running total. This will take O(n) time, where n is the length of the list.
Reverse a Linked List Using Recursion
AskAI
Algorithms, Data Structures and Coding
This problem involves reversing a linked list using recursion. The given example input is a list of integers, but this technique can be applied to lists of any data type. The output should be the reverse of the input list.
Anagrams in a List
AskAI
Algorithms, Data Structures and Coding
Given a list of words, this code problem finds all of the anagrams in the list. For example, given the input ["cat", "tac", "act", "dog ", "god", "gdo"], the output would be [["cat", "tac", "act"], ["dog", "god", "gdo"]].
Get Second to Last Node in Linked List
AskAI
Algorithms, Data Structures and Coding
Write a function that takes a linked list as input and returns the second to last node in the list.
Recursive String Reversal
AskAI
Algorithms, Data Structures and Coding
This technical problem involves implementing a function that reverses a string using recursion. For example, given the input string "Hello", the function would return the output string "olleH".
