Hi ,

Check Out SEGMENT EDU of codeforces for starting segment i think they are a >=1300 and <=2500 — [here] & [here]

And this is a few problem:

[1700 — Xenia and Bit Operations]

[1900 — Subsequences ]

[1900 — Enemy is weak]

And this is a few problem WITH over 2000 but not too hard:

[2100 — Water Tree ]

[2200 — Valera and Queries ]

[2200 — Yaroslav and Divisors ]

[2200 — Monsters (hard version) ]
