Gave CC div4 was able to first 4 problems fairly easily but 5 got me. Got stuck of a silly logical error, but I do have a feeling of break through. Will upsolve it for sure.

Gave cf div 4, was able to solve 3 question but tle on 4th got me for goood But definitely upsolved it after the contest, the key insight I got was to make all changes in seperate vector delta and at end for all print it while summing it the original vector

Also just wrapped up the @codeforces div 2 contest A=> Was simple created vector of pair of int and char and then sorted this and checked for adjacent same colors B=> In this to looked for the cases of MEX & found if no 0 impossible or freq[0]>1 and no one then also not possible

Gave first Contest @atcoder A=> Was getting WA at p<=100 x instead of 99 B=> Solved it using brute approach and creating a function to check for the language will upsolve C by changing approach couldn't pass few test cases

Built a simple Color Picker App using React 🎨 This helped me clearly understand how useState works with real-time UI updates. Changing the color updates the state, and the UI reacts instantly It’s a small project, which is contributing to my learning #WebDev #BuildInPublic

Gave CC Starters 221 in Div 4 Was able to solve first 4 questions; For the second one you had to greedy for the jacket and comparison again Third took several attempts but then if freq is greater than 2 then it becomes impossible to get ans For fourth made a function to check odd

Been spending the last few weeks getting comfortable with React ⚛️ Focusing on the basics : -passing data using props - component reusability – conditional rendering – PropTypes &defaultProps – rendering lists with map() Enjoying the process , one step at a time;

Gave Cf Div 3 yesterday Solved Problem A fast enough. For B, I went straight into simulation and missed the key observation: when s > k, even turns give k sand on the last flip, odd turns give s. Then just could not concentrate for the C, will upsolve C today itself;

I went quiet here for the last 2 months. College exams took over, routines broke, and consistency slipped. I didn’t quit learning — I just stopped posting. Showing up again, imperfect but intentional. Let’s go.
