Being an engineer there are such a lot of issues that I’ve to unravel on daily basis that you just get into the stream fairly simply. However at work you might be principally fixing the identical kind of issues every day that you just overlook that there are different thrilling sorts of issues on the market that require you to suppose otherwise. A fantastic beginning place is Leetcode or another day by day coding puzzle web site. Let’s go over easy methods to get began and greatest practices!

The first step is to learn the issue and perceive the instance options that they provide you. Work by means of the examples on paper if it’s a must to, break down every drawback right into a sequence of steps to work towards the answer. Begin desirous about potential edge circumstances that aren’t thought of that your design must have in mind.

Step two is to jot down some abbreviated pseudo code. I have a tendency to consider this step just like the high-level whiteboard coding interview. Run by means of the algorithm you’ll use to unravel the issue. Write down any information buildings that you just may want and ponder the time and house complexity. That is the best step to repair, however after I get caught that is the work I refer again to to assist get me again on observe.

Step three is to code your check circumstances. Now that you’ve got a good suggestion of what that you must do, write some further exams and write your check circumstances in code in case you are coding exterior of their editor. Leetcode received’t inform you what exams failed exterior of those they provide you (possibly they do if in case you have premium? Unsure tbh)

Professional tip: Code in your editor. Not within the browser.

Step 4 is to code and iterate in your design. Simply because it passes all of the exams doesn’t imply it’s good. Consider potential optimizations or methods to make your code extra versatile.

Step 5 is to have a look at what different folks did and see if there’s something you’ll be able to study from their strategy to the issue. There are sometimes a number of options so don’t be stunned if you happen to see one thing barely completely different.

Right here’s the record of each Leetcode drawback I solved
