Question 1: Algorithm Optimization Problem Statement: You are given an implementation of a function which accepts as input a non-empty zero-indexed array A consisting of N integers. The function works slowly on large input data and the goal is to optimize it so as to achieve better time and/or space complexity. The optimized function should return the same result as the given implementation for every input that satisfies the assumptions. Examples: For example, given array A such that: A[0] = ...
