Day of Studying LeetCode Solution until I Can Solve One on My Own Problem Best Time to Buy and Sell Stock Easy JS Intro I am a former accountant turned software engineer graduated from coding bootcamp Algorithms and Data Structure is an unavoidable part of interviews for most of the tech companies now And one of my friends told me that you need to solve a medium leetcode problem under seconds in order to get into the top tech companies So I thought I d start learning how to do it while job searching Since I have no clue on how to solve any of the problems even the easy ones I thought there is no point for me to waste hours and can t get it figured out Here is my approach Pick a leetcode problem randomly or Online Assessment from targeted companies Study solutions from Youtube or LeetCode discussion section One brute force solution another one more optimal Write a blog post with detailed explanation and do a verbal walk through to help understand the solutions better Code out the solution in LeetCode without looking at the solutionsCombat the forgetting curve Re do the question for the next three days And come back regularly to revisit the problem Best Time to Buy and Sell StockDifficulty Easy Language JavaScript You are given an array prices where prices i is the price of a given stock on the ith day You want to maximize your profit by choosing a single day to buy one stock and choosing a different day in the future to sell that stock Return the maximum profit you can achieve from this transaction If you cannot achieve any profit return Example Input prices Output Explanation Buy on day price and sell on day price profit Note that buying on day and selling on day is not allowedbecause you must buy before you sell Example Input prices Output Explanation In this case no transactions are done and the maxprofit Constraints lt prices length lt lt prices i lt Solution My first though is to find all possible profits and get the max profit with two for loops but that exceeds the time limit Key to solve this problem is understanding that stock can only be sold after it s bought We will set the prices on day one as purchase and loop through the prices array If a higher price is seem on the next day save profit made by subtracting purchase price from the higher price Note that the profit will be constantly updated whenever a new higher profit is found If a lower price is seem on the next day set it as the new puchase price Note the purchase price variable will be constantly updated whenever a new lower price is seem When the loop ends the final profit is our answer var maxProfit function prices let purchase prices let profit set initial profit as and the prices on day one note as puchase price for let i i lt prices length i Loop note prices array starting on index as index is already set as purchase price if prices i lt purchase purchase prices i If note a lower price is seem on the next day set it as the new puchase price else profit Math max profit prices i purchase If a higher price is seem on the next day save profit made by subtracting purchase price from the higher price Note that the profit will be constantly updated note whenever a new higher profit is found return profit References LeetCode Problem LinkYoutube ThinkFWDNote For LoopNote Access an array item by its indexNote if elseNote Math max Blog Cover Image Credit |
