Problem Statement: You are given an array prices where prices[i] is the price of a given stock on the i th day. You may complete as many transactions as you like (i.e., buy one and sell one share of the stock multiple times). You must engage in a transaction before selling it. You are not allowed to engage in multiple transactions simultaneously (i.e., you must sell the stock before you buy again). Your task is to find the maximum profit you can achieve. Input Specification: The first line contains an integer n, the number of days. The second line contains n space separated integers, prices[0], prices[1], ..., prices[n 1], representing the stock prices on each day. Output Specification: Output a single integer, the maximum profit that can be generated. Constraints: Constraints were not explicitly provided in the original content, but generally for competitive programming problems of this type, n can be up to 10^5 and prices[i] up to 10^9. Sample Test Case: Input: 6 7 1 5 3 6 4 Output: 7
