Code Problem
Shortest Path in a Directed Graph
AskAI
This technical problem deals with finding the shortest path between two nodes in a directed graph. An example input and output is given in the problem description.
Reversing a Singly Linked List
AskAI
To reverse a singly linked list, we simply need to iterate through the list and reverse the pointers of each node. This can be done in place, without creating a new list.
Binary Search: Find Target Value in Sorted Array
AskAI
This problem requires the use of a binary search algorithm to find a target value in a sorted array. If the target value is found, the index of that value is returned. If the target value is not found, -1 is returned.
Binary Search
AskAI
This problem involves searching for a given value in a sorted array of integers. If the value is found, the index of the target value is returned; if not, -1 is returned.
Longest Path in a 2D Array
AskAI
Given a 2D array of integers, find the longest path of consecutive integers starting from the top left corner of the array. The path can move in 4 directions: up, down, left , or right.
TwoSum: Find Two Numbers That Add Up to a Specific Target Number
AskAI
The twoSum function should return the indices of two numbers in an array that add up to a specific target number.
Binary search for target integer in array.
AskAI
This problem deals with finding a target integer within a large array of integers. The function should return the index of the target integer if it is found, or -1 if it is not found .
Shortest Path in a Graph
AskAI
This problem deals with finding the shortest path between two vertices in a graph. A data structure is needed that can efficiently find this path.
