💻 Day 41 of #100DaysOfCode

Classic Fibonacci recursive solution- but this time in Java for me!
This was much easier than a different recursive problem I had to work on 😅
Screenshot of visual studio code of my Lab 5 which shows the purpose, parameters and return values of a classic Fibonacci problem as well as my two line code for recursive calling of fibonacci; plus two example problems.

💻 Day 40 of #100DaysOfCode

The before and after I optimized today's daily Leetcode for Big O time complexity :D I was using a full on 2D matrix at first so that I could visualize this literal spreadsheet. After submitting I realized no one is seeing this sheet so I can make it a dictionary instead!
Leetcode #3484. Design Spreadsheet. My first accepted solution beat only 9% of other solutions with a runtime of 797ms. Leetcode #3484. Design Spreadsheet. My second solution beat 66.67% of solutions with a runtime of 187 ms, significantly better. On the right you can see the start of my solution where I initialize a dictionary instead of a 2D matrix.

💻 Day 39 of #100DaysOfCode

Hi all! Lots of exciting things happening in my world of code. ✨

I solved a leetcode-style problem for my Java class today, am continuing to work on two React JS projects with some friends, started dabbling with Lua through Solarus, aaaand did #9 in Leetcode.
#9 Palindrome Number accepted solution. On the left: Runtime 8 ms Beats 52.25% Memory 17.98 MB Beats 19.95% On the right, my solution code that turns the number into a string, then uses a for loop to check that one half of the number matches the other half. My Java solution for “isSameEventSequence” shows using a stack and enacting the push/pop events to determine if two arrays have matching event sequences. Lots of comments to explain my work throughout. Sneak peek to part of my main timer code that’s written in ReactJS.

💻 Day 38 of #100DaysOfCode

Started my DSA class yesterday, and it’s going to be in Java (gasp!)
Worked on my first lab with the target sum premise, solved it with the non-optimal solution and the hashmap solution.

Java's not my favorite but I learned more about hashmaps in Java with this problem
A screenshot of my lab code for getIndices() where I show two solutions. O(n) uses a hashmap and goes through the array of numbers just once. O(n^2) solution uses nested for loops to try to find the right indices.

💻 Day 37 of #100DaysOfCode

Completed today’s Leetcode Daily Problem: #3446. Sort Matrix by Diagonals (medium). Not the most optimal in terms of runtime, but the memory was decent!

Going through nested arrays always makes me think of using nested for loops- just me? 👀
A solved Leetcode daily question for sorting a matrix by its diagonals. On the left, the “Accepted” screen for 1306 test cases passed; a 21ms runtime that beats only 20% of solutions & 17.76mb memory that beats 83% of solutions. On the right, the start of my solution that uses nested for loops, sorting, and print statements for debugging.

💻 Day 36 of #100DaysOfCode

Completed a quick Clash of Code on CodinGame where you’re given a log of parentheses and you need to determine what floor the elevator ended up on. “(“ meant 1 floor up, and “)” meant 1 floor down.
My submitted Clash of Code solution. My solution starts on line 14 where I create a currFloor variable and then a for loop to go through each bracket given.

🚧 Worked on today’s Leetcode problem. I think I'm close but feeling fuzzy so I haven’t solved it entirely. Posting now before I forget! Will try to work on it later.
Leetcode #1277 Count Square Submatrices with All Ones. On the left a description of the problem with examples. On the right my partial program with some printouts at the bottom in the test result section.

💻 Day 34 of #100DaysOfCode

Today’s Medium Leetcode was a fun one for me because it had me searching “factorial for addition” lol and it reminded me of an existing formula for that! Even though I didn’t solve it optimally, I’m glad I got a solution for this problem.

Yay Coding! 💻
Completed Leetcode #2348. Number of Zero-Filled Subarrays. Left shows Accepted solution with Runtime of 73ms that Beats only 11.65% of solutions. On the right it shows the start of my solution with a lot of variable set up and creating subarrays for each new set of zeros.

Day 33 of #100DaysOfCode

Big Milestone yesterday as it marked the end of my job as Snap Engineering Academy Coach! It was such a wonderfully rewarding experience and I’m so excited to see what our scholars do next. 💛

Here’s two easy Leetcode problems I did this morning :)
“maximum69Number” problem with 0ms runtime, my solution shows I converted the int variable to string and using a for loop to go through each digit. “isPowerOfFour” problem with my 2-line solution where I run: while n > 1: n/=4 return True if n == 1 else False with a 0ms Runtime

After over 7 years, I've officially beat all Flow levels 🥳😄
One of my favorite casual puzzle games, this is one of the few games I bought the ad-free version for and it's given me actual years of fun. Thank you Big Duck! 🦆

- Attempted today’s hard Leetcode problem of Rearranging Fruits (passed 4 test cases where only 1 swap is needed)
- Completed yesterday’s Leetcode problem for Pascal’s Triangle
Leetcode’s #2561 Rearranging Fruits shows the description on the elft and my attempted solution on the right. Leetcode’s #118 Pascal’s Triangle with my accepted solution on the right with many comments including input output, and solution description. Runtime on the left “beat” 100%

Day 31 of #100DaysOfCode

Today I worked on an easy Leetcode problem to boost my confidence.
(note to self - though I've been coding more often, I'll just count every post as a day)
Some other things I've been doing: deploying a react site via github, coaching eng scholars, and reviewing DSA
