There is a tree which denotes 4 directions,
Node direction{
direction *side1,*side2,*side3,*side4;
};
makeTree(){
direction *tree;
getdirection(tree,1);
getdirection(tree->right,2);
getdirection(tree->left,1);
/*
how to form such a tree
root
side1 side2
side3 side4 side1 side2
*/
}
getDirection(Node *node,int val){
if(val == 1){
//should form direction to side1,side2
}else if(val == 2){
//should form direction to side3,side4
}
}
