    巧了==不过我代码短那么一点点==
    ~~~c++
    #include<iostream>
    using namespace std;
    int m,n,cnt;
    void dfs(int h,int t){
    if(t==0){
    cnt+=!(h^1);return;
    }
    if(h!=1) dfs(h-1,t-1);
    else dfs(n,t-1);
    if(h!=n) dfs(h+1,t-1);
    else dfs(1,t-1);
    }
    int main(){
    cin>>n>>m;
    dfs(1,m);
    cout<<cnt;
    }
    ~~~
