记录每个牛的生肖，然后按照每一条提示算出与那个万恶的Bessie之间生肖的关系。

#include <bits/stdc++.h>

map<string, int> x, name, ans;
int main(){

    name["Bessie"] = 2; ans["Bessie"] = 0;
    for(int i = 1;i<=n;i++){
        string a, b, c, d;
        cin >> a >> b >> b >> b >> c >> d >> d >> d; //读掉一些不需要的东西
        name[a] = x[c];       //记录生肖
        if(b[0] == 'p')  //pre
            if (x[c] < name[d]) ans[a] = ans[d] - name[d] + x[c];

        else  //next
            if (x[c] > name[d]) ans[a] = ans[d] + x[c] - name[d];
            else ans[a] = ans[d] + 12 - name[d] + x[c];
    }
    printf("%d\n", abs(ans["Elsie"]));
    return 0;
