ACM-ICPC INC 2014 – Indonesia National (Programming) Contest – was held on 9th November 2014 with more than 350 participating teams (of three students) from various universities in Indonesia. As usual, INC serves as the qualification round for teams from Indonesia who want to compete in ACM-ICPC Regional Jakarta, which this year’s will be held in December. However, unlike any previous years, Indonesian teams now have other means in order to qualify to ACM-ICPC Regional Jakarta, i.e. become the top 5 in CompFest or top 5 in ICPC Provincial Sumatra (see my previous post about this contest).

In this post, I will discuss each problem posed in the contest. There are 10 problems, from A to J. Link to each problem, along with the problem discussion, can be found on the following pages:

Or you can read my note about this contest on the last page: Notes.

If you want to comment or ask a particular problem, please mention which problem are you referring to (note that this is a single post, with multiple pages).

  1. “One popular approach was by first sorting all the strings and pair each succesive string whenever possible”, kode saya spt itu, hanya saja pasangkan dr yg terpanjang http://ideone.com/PGjPAq

  2. komen untuk prob J

    β€œOne popular approach was by first sorting all the strings and pair each succesive string whenever possible”, kode saya spt itu, hanya saja pasangkan dr yg terpanjang http://ideone.com/PGjPAq

    • koreksi, prob G

    • Ngga, kode kamu nggak seperti itu. Approach kamu itu jadi sama dengan approach greedy yang bener (pasangin dari leaves) — string yang paling panjang saat itu pasti leaf.

      Yang dimaksud “pair each succesive string whenever possible” itu comparenya bener-bener cuma sama 1 string di sebelahnya aja (sorted); sedangkan kamu compare dengan yang panjangnya lebih pendek.

  3. a bit curious about problem H. Did you use the real Kawal Pemilu data for judge’s test case? πŸ˜€

  4. nice problem, nice editorial, pretty helpful, thx πŸ™‚

  5. saya penasaran dgn problem yg blm sempat saya kerjakan (dan AC), apakah mungkin akan diupload ke situs online judge ?

    saya dpt ide sederhana utk problem J dgn menelusuri apakah suatu nilai bisa jadi pivot (menjadi ‘L’), setelah itu cek apakah bs dr index tersebut menjadi good segment, jika tidak cetak impossible, kode saya : [[REMOVED]]

    thx koreksinya πŸ˜€

  6. How about ACM-ICPC 2014 Jakarta write up?? Will it be published?

  7. How can I get input data ?

    Thank you for sharing.

    • Ah… I didn’t notice this comment before >.< I'll not share the input data publicly. You can test your solution in some online-judges, e.g., tokilearning or joj. (I think) I have sent the test data to the admin on those sites.
