(Rant) Being a cs major, why do colleges teach us stupid ass subjects like maths (NOT RELEVANT TO CS), Mechanical engineering, electrical engineering, Chemistry and TF BIOLOGY!🫠 And this is the condition of a top 15 engineering college of India!💀

#DSA Day 1 humbled me HARD fr 😭 Thought I'd breeze through easy array problems! nah. 1st: 2 mins, clean AF 2nd: 40 mins + peeked pseudocode 3rd: O(n) optimal but code? trash Learning in public hurts but grows fast. Thread of what actually clicked 👇 #LeetCode #100DaysOfCode

Was revising #Java Arrays for #DSA prep… and got stuck: Why does ArrayList resize by 1.5× instead of doubling (2×) or even 0.5×? 🤔 Turns out 1.5× is the sweet spot: -2× wastes too much memory -Smaller factors → frequent resizes → worse time Java's designers nailed it!
