Bangladesh Advanced Computing Society (BACS) organizes annual training camps for ICPC regional participants in different venues all across Bangladesh. For this, BACS takes an online selection contest. This year BACS decided to accommodate BdOI participants as well. To select them, an onsite contest was held simultaneously in 5 different cities. To know more about BACS, you can check their website.
The contests had 8 and 7 problems respectively and were held in IOI format. We decided to merge the three give away problems into one. Adding that with the other 12 problems, we created an ICPC style set with 13 problems.
The replay contest will take place on Friday, August 10, 2018, 4 PM MSK in Codeforces Gym, and will run for 5 hours.
Problems used in this contest were prepared by Alpha_Q, aminul, codename27, flash_7, Imran_Bin_Azad, ISwearItIsMyLastContest, Jami_CSEDU, kimbbakar, Maxon5, prophet_ov_darkness, raihatneloy, s_h_shahin, Sherlock221b, shovonshovo, tube_light, and Z0RR0.
UPD 1: Contest will take place on Friday, August 10, 2018, 4 PM MSK, instead of Saturday, August 11. Codeforces Round #503 (by SIS, Div. 1) was supposed to take place on Friday, August 10 initially. The CF round has now been postponed to Saturday, August 11; and it clashes with the time we proposed earlier for this replay contest. We are shifting the contest to Friday, August 10 to avoid the clash. Sorry for notifying everyone this late.
UPD 2: Editorial has been published.
