WFH Day 205
I’m currently working on some very tricky programming issues at work. Things are moving slowly, and there are times when I think what the hell am I doing here. Luckily, this is a temporary state and will only get worse by working on something entirely different. Right, working on the leetcode October challenge can show me that things can get worse. Last night I spent 3 hours! On a simple (in retrospect, it was a straightforward) problem. Inserting something into a BST and return the resulting BST. Perhaps it was too late, I didn’t pay enough attention to the little details along the way, but I got something working on my machine, and when I pasted it into the leetcode editor, it wasn’t working anymore. Great! WHY IS THIS NOT WORKING?! I got it working locally, and now this. Sigh. I didn’t get the points for that day, and I went to bed slightly frustrated about the outcome. Anyway, it should be fun and entertaining, but it wasn’t.
Early this morning, I looked at the problem again and tried several things to debug the issue to make it work in leetcode. And then I finally found the stupid mistake I made. So, I could fix it and throw away 60% of my solution, since the code I wrote to turn an array with numbers into a BST was unnecessary at all. Since the input from the test case looked like an array, I built some function to create a BST from that serialized BST and then insert the new number into the BST. But the test case input was already an instance of the BST, and I just needed to binary search that tree and insert the value at the correct spot.
- read the instructions carefully
- inspect the input data from the test cases
- don’t do it late at night
Anyway, I solved the problem today much more comfortable by being more careful. And the Oakland Athletics won the 3rd game of the postseason beating the sh** out of the Astros. Go A’s!!!
BTW: If you want to know how it feels about interviewing for a software engineering position at some high profile companies, I recommend watching this analogy for when the same principles apply for doctors.
