To find the longest sequence of consecutive integers in an unsorted array with O(n) time complexity, use the following approach: Insert all elements into an unordered_set, which prvoides average O(1) lookup time and atuomatically removes duplicates. Iterate through each number in the set. Only start counting a sequence if the current number is ...

Data Structures A data structure is a way of organizing and storing data in a computer so that it can be accessed and modified efficiently. It defines the relationship between elements within a collection. Algorithms An algorithm is a well-defined computational procedure that takes input values and produces output values. Essentially, it's a se ...

Binary Search Fundamentals Problem Statement Given a sorted array of n integers in ascending order and a target value, implement a function that searches for the target in the array. Return the index if the target exists, otherwise return -1. Constraints: All elements in the array are unique n ranges from [1, 10000] Each element falls within [ ...
