Interview Round: Technical Screen
##### Scenario
Online assessment requiring implementation of common algorithmic problems.
##### Question
Given an array of integers and a target, return indices of the two numbers that add up to the target (assume exactly one solution).
2) Given a string, determine the length of the longest substring without repeating characters.
##### Hints
Use hash maps for O(n) solutions; mind edge cases like empty input.
Quick Answer: This question evaluates proficiency in fundamental algorithmic problem-solving, specifically array manipulation, string processing, and the use of basic data structures along with performance and complexity reasoning.
