Helllo,,please,help me,to write programm add balance,delete balance in search tree,
TreeNode *AddBalance (Type x,TreeNode *root,int *grow)
{int incr;
*grow = 0;
if (!root)
{root=(TreeNode*) GetPlace();
if (root)
{root->left=root->right=0;
root->value=x; root->balance=0;
*grow=1;
}
return root;
}
if (x<=root->value)
{root->left=AddBalance(x,root->left,&incr);
if (incr)
{switch(root->balance)
{case 0:root->balance=-1;*grow=1;break;
case 1:root->balance=0;break;
case -1:
switch(root->left->balance)
{case -1:root=Rebuild_L1(root);break;
case 1:root=Rebuild_L2(root);
}
}
}
}
else {root->right=AddBalance(x,root->right,&incr);
if(incr)
{switch(root->balance)
{case 0:root->balance=-1;*grow=1;break;
case -1:root->balance=0;break;
case 1:
switch(root->right->balance)
{case 1:root=Rebuild_L1(root);break;
case -1:root=Rebuild_L2(root);

}
}
}

}
return root;
}
