ConstructiveChef :(

why is this wrong , div 2 A (stamps 100) Can someone please give a case for which it fails?

    void solve() {
        int n;
        cin >> n;
        string ch;
        cin >> ch;

        for (int i = 0; i + 2 < n; i++) {
            string s = ch.substr(i, 3);

            if (s == "110" || s == "111" || s == "101") {
                ch[i] = '1';
                ch[i + 1] = '0';
                ch[i + 2] = '0';
            }
        }

        cout << ch << endl;
    }

 

Any one who did concussive sequence?

Rank updating too slowly :|

When will the leaderboard update? It hasn't for nearly 70 minutes. :/

Edit: It's updating, but very slowly.

It's high time to learn System Design for Codechef team :[

While I enjoyed the problems, I'm disappointed to see that the contest platform is less functional than I remember. (For example, the scoreboard in Div. 1 didn't update for the last hour of the contest, the contest timers on the problem pages were off by several minutes so that I didn't realize the contest was over until two minutes after it had ended, etc.)

Horrible constructive problemset, bad queue issues, and ranklist is stuck

can anybody pls explain me why [2 2 2 2 2 1 1 1 1] this test case is giving -1 for concussive sequence its answer should be 2 1 2 1 2 1 2 1 2 but for someone's code it is giving -1 and that is accepted solution I don't know what am I missing

Hey all,

We’re sorry there were some major inconveniences for the participants. Submitting code to the problems had been working fine throughout, but other peripheral stuff (Run, ranklist, live ratings, etc) were getting backlogged, and for a bit the pages were also slow to load. The new judging system worked smoothly, but we seem to have underestimated the increased impact it’ll have on the DB, and so the DB got overloaded. We will positively fix the DB issue in a few days and post an RCA.

Apologies again, for the issues.

What have they done to codechef Have they improved it or downgraded it

For concussive sequence,my code gives WA.When i debug,it gives me following testcase and says output is wrong-

1
4
1 1 2 2

and my code output is 1 2 1 2. How is that wrong?? link to submission- link

No rank and score updates, long queues, constructive problems in div2 and also didn't understood why my code works fine for Ant and passes all test cases but it just does.
