⭐️⭐️⭐️ # 題目敘述 Given an array nums of integers, return the length of the longest arithmetic subsequence in nums . Note that: A subsequence is an array that can be derived from another array by deleting some or no elements without changing the order of the remaining elements. A sequence seq is...

⭐️⭐️⭐️ # 題目敘述 You are given an array prices where prices[i] is the price of a given stock on the ith day, and an integer fee representing a transaction fee. Find the maximum profit you can achieve. You may complete as many transactions as you like, but you need to pay the transaction fee for each...

⭐️⭐️⭐️⭐️⭐️ # 題目敘述 You are given two 0-indexed arrays nums and cost consisting each of n positive integers. You can do the following operation any number of times: Increase or decrease any element of the array nums by 1 . The cost of doing one operation on the ith element is cost[i] . Return the...

從測試、建置到部署一次自動化 # What is CI/CD? CI/CD 工具也是為了 DevOps 概念而產生的自動化工具，透過持續整合、持續部署的方式，在開發階段就自動協助開發人員偵測程式碼問題，並部署至伺服器。 # CI（Continuous Integration）持續整合 當開發人員完成一個階段性的程式碼後就經由自動化工具測試、驗證，協助偵測程式碼問題，並建置出即將部署的版本（Build）。 # CD（Continuous Deployment）持續部署 可以說是 CI 的下一階段，經過 CI 測試後所構建的程式碼可以透過 CD 工具部署至伺服器，減少人工部署的時間。 #...

ChienI Kao 筆記網站 JHTNT 筆記網站 # What is DevOps? DevOps 拆開來就是 Development + Operations ，也就是開發與維運。 更準確的說可以是「開發」「測試」「維運」三者的結合，是一種軟體開發和部署的方法論。 DevOps 主要促進開發和 IT 運營兩個團隊的結合與運作，提升團隊之間的協作和溝通。 DevOps...

⭐️⭐️⭐️ # 題目敘述 You are given a 0-indexed array nums of n integers, and an integer k . The k-radius average for a subarray of nums centered at some index i with the radius k is the average of all elements in nums between the indices i - k and i + k (inclusive). If there are less than k elements before...

⭐️ # 題目敘述 There is a biker going on a road trip. The road trip consists of n + 1 points at different altitudes. The biker starts his trip on point 0 with altitude equal 0 . You are given an integer array gain of length n where gain[i] is the net gain in altitude between points i ​​​​​​ and i + 1 for...

ChienI Kao 筆記網站 JHTNT 筆記網站 # 軟體框架 (Software Framework) 為軟體開發提供了一個基礎的架構、地基，去實現更複雜的軟體或是邏輯，使開發更有效率的進行，他扮演著規範和定義的角色。 框架本身無法自行運作，開發者必須將自己的程式搭配框架才是一個完整的應用程式。 運用框架其實就像把別人已經做好的零件拿來使用，就像要製作一台機器人，總不可能從製作螺絲開始吧！螺絲通常是像他人購買，而我們專注於完成機器人的整體。 而軟體架構就是如此，他提供了別人事先寫好的函式庫（Library）或類別庫（Class...

⭐️⭐️⭐️ # 題目敘述 Given a function fn and a time in milliseconds t, return a debounced version of that function. A debounced function is a function whose execution is delayed by t milliseconds and whose execution is cancelled if it is called again within that window of time. The debounced function...
