Continuous Median Given a stream of numbers, we want to calculate a continuous median. class ContinuousMedianHandler: """ A class to handle continuous median calculations for a stre…
Shifted Binary Search This code performs a binary search on a shifted sorted array to find the index of the target element. The shifted_binary_search function is a wrapper for the helper function …
Find Loop in a Linked List This case solves the problem of finding the starting node of a loop in a linked list. A node in a linked list with a loop exists where the next pointer points to a pr…
The Boggle Board problem The Boggle Board problem can be expressed as follows: Given a Boggle board consisting of n×m cells filled with characters and a list of words, the task is to find…
Search For Range Here's the problem illustration. Given a sorted array, and a target number e.g. 45, find the range of indices in the input array in between which you can find the target va…
HeapSort Algorithm A conceptual overview of the HeapSort algorithm The provided algorithm implements heap sort, a comparison-based sorting algorithm that leverages the heap data struc…
Quicksort Algorithm The provided code implements the quicksort algorithm, a highly efficient sorting algorithm known for its average-case performance of O(n log n) and ability to operate…
Quickselect Algorithm The quickselect algorithm seeks to find the kth smallest value or the kth largest value in an input array in linear time on average and a constant space complexity if the alg…
Longest Substring Without Duplicates In this question, I hope to help you find the longest substring without duplicates by first getting the conceptual overview right. I will then proceed to explo…
Underscorify Substring In this question, you are provided with two strings. The first one, called the main string is the longer string. The smaller string is also called the substring. The obje…
