![]() ![]() We will also use a char to map 62 characters and digits so we can encode the short URL in a custom base 62. We will be using a hash map to keep associated the long and the short URL. + code(codec.encode(longUrl)) + " hm = null Later we take the resulting string and we need to return the original one. To solve this problem we need to take a string and convert it to another. Something we should consider is the concept of Bijection. In addition, note how LeetCode will be testing our implementation. The name of the class and the two required methods are shown. Your Codec object will be instantiated and called as such: Decodes a shortened URL to its original URL. Since I will use my computer, in addition to solving the problem, we will be generating a test scaffolding. The simplest approach is to directly solve it in the LeetCode web site using the provided IDE. #System design tinyurl windows 10I will develop the code using the Java programming language on a Windows 10 machine using the VSCode IDE. Note that we can do whatever we want in the required methods. We need to design the encode() and decode() methods that will take respectively a long URL and convert it to a short URL and vice versa. They have been replaced in order to reduce space and to hide information about where the video clips are stored. I will take a look at it later this week.įor example, if you watch YouTube videos (and who does not), chances are that you have noticed that the URLs are somewhat different to most URLs. You just need to ensure that a URL can be encoded to a tiny URLĪnd the tiny URL can be decoded to the original URL.Īpparently there is a companion problem. ![]() There is no restriction on how your encode/decode algorithm should work. TinyURL is a URL shortening service where you enter a URL such as:ĭesign the encode and decode methods for the TinyURL service. Note: This is a companion problem to the System Design problem: This seems a topic that we could better relate to. In this post we will deal with LeetCode 535 “ Encode and Decode TinyURL”. After getting ready, I will work for a few hours. Today I will finish this post, prepare and have breakfast with my wife. About 03:30 PM the delivery was made and two technicians put the unit together. Around 03:00 PM we all headed to his place to chat while waiting for the delivery. ![]() My son took two slices home to share with his family. My son showed up at our place around 01:00 PM. She just watches me switch tasks while having yogurt with homemade granola and warm milk with a triple espresso. I do it while chatting with my wife during breakfast. I can take all the ingredients, mix them and put the dough to rise in about 25 minutes. In the past couple years I have switched to using our Kitchenaid mixer. The delivery was scheduled between 03:00 PM and 06:00 PM.Įarlier that day I had made some pizza dough. ![]() They were expecting a delivery and installation of a piece of exercising equipment. My daughter in law was going to visit her family and my son had to stay home. Yesterday I worked all morning (about 6 hours). It seems that time is flying by faster than ever. ![]()
