Leetcode Weekly Contest 420 PASS|PASS|PASS|FAIL
I'm giving the Leetcode Weekly 420 contest another shot! 💪 I stumbled a bit on the 3rd task by misreading the conditions and second-guessing my initial solution. The last one was a real challenge 😅, and with limited time, I couldn’t pull together an efficient approach—brute force would’ve struggled with those tree branches 🌳. Plus, half of my ideas about child subtrees turned out to be off, since I didn’t properly account for the parent node—it should come after all the children are visited, not midway as I suggested during brainstorming. But I’m staying upbeat and motivated! 🚀 Practice makes progress, and that’s my mantra! ✨
