This technical problem involves determining whether a route exists between two nodes in a directed graph. An example input and output are given.
Printing the median of a stream of integers.
AskAI
Algorithms, Data Structures and Coding
This problem deals with printing the median of a stream of integers. At each time step, the median of the integers received so far is printed out.
Non-repeating character in a string
AskAI
Algorithms, Data Structures and Coding
This problem is about finding the first non-repeating character in a string. For example, if the input string is "GeeksforGeeks", then the output should be 'f '.
"Sum all elements in an array"
AskAI
Algorithms, Data Structures and Coding
This technical problem involves finding the sum of all elements in an array. The input is an array of integers, and the output is the sum of all elements in the array.
Maximum Depth of Binary Tree
AskAI
Algorithms, Data Structures and Coding
To find the maximum depth of a binary tree, we can use recursion. First, we need to check if the tree is empty. If not, we need to find the maximum depth of the left and right subtrees. The maximum depth of the tree is the maximum of the left and right subtrees' depths, plus one.
"Finding the Shortest Path in a Maze"
AskAI
Algorithms, Data Structures and Coding
This problem is about finding the shortest path through a maze. The input is a 2D array representing the maze, and the output is the shortest path from the top-left corner to the bottom-right corner.
Implement binary search function
AskAI
Algorithms, Data Structures and Coding
The problem asks you to implement a binary search function that takes in a sorted array of integers and a target integer. The function should return the index of the target integer if it is found in the array, or -1 if it is not found.
