Hi everybody :D
One week ago i've participated in the APIO2016 and my score was 61 and it's very bad , i felt like a looser so i stopped the IOI Training contests , but now i have pushed the reset button and returned to my normal mood :D
so i'm going to invite to participate in the IOI Training Contest #4 .
the problems are from USACO 2012 November Contest 2 gold 2 silver as usual .
it will be held in 17/May/2016 on 18 MSK .
the contest's duration is 5 hours as usual .
the contest's URL : https://www.hackerrank.com/ioi-training-contest-4 .
i will add the names of the top 3 competitors and the links to the tutorials to the post after the contest .
and let's discus here about the problems after the contest :D
hope u enjoy and learn :D
i've something i would like to talk about , why we don't make the IOI training contests UNRATED public contests just like the educational rounds ?? there are a lot of volunteers who can prepare new problems , we don't need very hard problems we only need useful problems , just think about it and write your opinions in the comments , ** thanks anyway **:D
NOTE the IOI Training contests are some contests that i prepare and participate on to train myself the others on such contests style before the IOI2016 .

the problems gonna be from USACO 2012 January .

Hello , this year i qualified to the IOI , so to get ready for that i think the best way is participating in contests but as everybody see the ioi style contests are so rare , so i decided to add an old contest (USACO , COCI , COI , etc...) every three or four days and participate on it.
so i'm going to invite you to join me and participate on those contests .
i will add the contests to Hackerrank , and i will post the time and the description here on codeforces .

the first contest will be held on Apr/19/2016 at 18 MSK , the contest's duration is 4 hours and the problems are from USACO 2012 February Contest there will be four problems 2 gold and 2 silver .
