#include <iostream> #include <fstream> #include <cstdio> #include <cstring> #include <cmath> #include <algorithm> #include <functional> #define inf 0X3f3f3f3f using namespace std; typedef long long ll; const int MAXN=1e9+10; const int MAX=100000+10; int main(){ #ifdef ONLINE_JUDGE #else freopen("in.txt","r",stdin); //freopen("out.txt","w",stdout); #endif char s[300],s1,s2; int time; s[118]=0; s[60]=1; s[94]=2; s[62]=3; scanf("%c %c",&s1,&s2); cin>>time; int a=s[s1],b=s[s2]; if(time%2==0){ cout<<"undefined"<<endl; } else{ if((a+time)%4==b) cout<<"cw"<<endl; else cout<<"ccw"<<endl; } return 0; }
