Program to Refactor

int mystery(int v1, int v2){
if( (v1 < 1) || (v2 < 1) ) return 0;
if( v1 < v2 ) return mystery(v1, v2-1)+1;
if( v2 < v1 ) return mystery(v1-1, v2)+1;
return mystery(v1-1, v2-1);
}
Your Improved Version

int mystery(int v1, int v2){
if( (v1 < 1) || (v2 < 1) ) return 0;
if( v1 < v2 ) return mystery(v1, v2-1)+1;
if( v2 < v1 ) return mystery(v1-1, v2)+1;
return mystery(v1-1, v2-1);
}
