Hello Codeforces,

I like to code. Entered CP in late 2026; I almost quit cuz it was too hard, but the stuff that's hard is always good.

Looking forward to participating in the Zonal Computing Olympiad (ZCO), the first stage for the Indian Computing Olympiad (ICO). Missing out on ZCO-2026 was a big shame for me, so I want to qualify in the upcoming year.

The Strat

The exam is held on CodeChef, so I'll start practising more there (forgive me, Mike) and, at the same time, write these blog posts to keep going!

• using the CSES problem set
• solving 1100- to 1300-rated CF problems (cuz for some reason these are just better structured)
• solving 1400- to 1500-rated CF problems
• fixing my contribution on CF (it's $$$ -25 $$$ )

Simple as that.

ZCO Blog 1 done!
