Design an algorithm to search for the longest string in a list and return its index.
list = ["apples", "bananas", "kiwis"]
#Requirements#
- Your algorithm should have a time complexity of O(n), where n is the length of the list.
- Your algorithm should have a space complexity of O(1), meaning it should use a constant ... | codefeedback | [

Develop a function that not only verifies the existence of a specific element within a predetermined numerical array, but also returns the positions of its duplicates if any, in descending order. An exception should be thrown if the array is empty. The algorithm's time complexity should not exceed O(n).

You are given a 2D grid representing a maze, where each cell in the grid can be either empty or blocked. The goal is to find a path from the top-left corner to the bottom-right corner of the grid, moving only through empty cells. You can move in four directions: up, down, left, or right. You need to implement a functio... | codefeedback | [
