Neural Feud

Progressive hints first, then the full explanation and implementation when you're ready to cash out.

Hints

Progressive nudges

Open only as much as you need to keep the solve alive.

There are only $8$ possible inputs. If you are reaching for suffix arrays, please step away from the keyboard.

The statement asks normal-looking questions, but the title is doing work. “Neural Feud” should sound suspiciously like Family Feud .

In Family Feud, the correct answer is not necessarily the true answer. It is the most common surveyed answer.

Here the surveyed group is not people: it is $15$ AI models. For each question, output the modal answer among those models.

The needed answers for $n=1..8$ are: $\texttt{walk}$ , $\texttt{no}$ , $\texttt{no}$ , $\texttt{no}$ , $\texttt{yes}$ , $\texttt{yes}$ , $\texttt{backwards}$ , $\texttt{seven}$ .

Editorial

Full explanation

Open this when you want the whole argument, complexity included.

Key Observation

This is an April Fools special problem, so the “algorithm” is mostly realizing what game is being played. The title Neural Feud is a parody of Family Feud.

In Family Feud, you do not answer with the objectively correct fact. You answer with the most common response from a surveyed group. Here, the surveyed group is $15$ AI models.

So for each input

1 \le n \le 8,

we output the most common AI-model answer to question $n$ .

Answers

The modal answers are:

\begin{array}{c|c} n & \text{answer} \\ \hline 1 & \texttt{walk} \\ 2 & \texttt{no} \\ 3 & \texttt{no} \\ 4 & \texttt{no} \\ 5 & \texttt{yes} \\ 6 & \texttt{yes} \\ 7 & \texttt{backwards} \\ 8 & \texttt{seven} \end{array}

Then the implementation is just a lookup table. No hidden data structure, no DP, no graph theory. Just hardcode the damn survey results and leave before the joke gets you.

Complexity

We read one integer and print one string.

\text{Time} = O(1), \qquad \text{Memory} = O(1).

Solution

Generated C++

This is the full implementation the model produced for the problem.

#include <bits/stdc++.h>
using namespace std;

using ll = long long;

void setIO() {
    ios::sync_with_stdio(false);
    cin.tie(nullptr);
}

int main() {
    setIO();

    vector<string> ans = {
        "",
        "walk",
        "no",
        "no",
        "no",
        "yes",
        "yes",
        "backwards",
        "seven"
    };

    int n;
    cin >> n;
    cout << ans[n] << '\n';
}

#include <bits/stdc++.h>
using namespace std;

using ll = long long;

void setIO() {
    ios::sync_with_stdio(false);
    cin.tie(nullptr);
}

int main() {
    setIO();

    vector<string> ans = {
        "",
        "walk",
        "no",
        "no",
        "no",
        "yes",
        "yes",
        "backwards",
        "seven"
    };

    int n;
    cin >> n;
    cout << ans[n] << '\n';
}
