As much as 70% of our time should be spent in steps 1-3. You want to make sure you completely understand the problem.
A good test of this is whether or not you can explain the problem to someone else.
It is very important to solve the problem manually first, so that you know what you are going to automate, otherwise you are just slinging code around.
Which while can be fun, will make you look like an idiot in a programming interview and will probably cause you to sweat profusely.
You want to be aware of each step, it is easy to gloss over them.
Let’s look at a very basic example, reversing a string.The most common mistake I see when conducting interviews or watching someone try to solve a programming problem is they try to start writing code as soon as possible. You really want to make sure you take enough time to understand the problem completely before attempting to solve it.Another big mistake is trying to over solve the solution on the first iteration. I am going to give you a simple set of steps to follow which you can use for any algorithm type programming problem. You may even want to read the problem 3 or 4 times.You should be tempted to actually write the code for this.That is good, it tells you that you have solved and simplified the problem well. Many times you can skip this step if you have a really good handle on the problem or your previous steps already created a detailed enough description of the solution that coding it is already a 1 to 1 translation.It’s well worth the effort to try and optimize the actual solution or simplify it when it is still in the most easily malleable state.What you want to do here is figure out if there is another way you can solve the problem easier, or if there are some steps you can cut our or simplify.The most severe of those is the improper allocation of time.If you have heard the saying “measure twice and cut once,” then you are probably familiar with the idea of spending upfront time to make sure something is done right, rather than diving right in.If I give you a string “Zebra”, and ask you to reverse it, most people will do the following manual steps. People often don’t realize how valuable this step is.It is much easier to rearrange and reconstruct and idea or algorithm in your head than it is in code.
