(b) Iterative deepening DFS (IDDFS) is a tree search strategy "...] in which a depth-limited version of depth-first search is run repeatedly with increasing depth limits until the goal is found." It's often used in game tree exploration, e.g. solving chess, as it allows for more efficient exploration of the space of possibilities, especially at earlier levels of the tree. Fill in the blanks below to implement IDDFS. class TreeNode public: TreeNodeleft, right; T valuei int height: // root node stores tree height; a single node tree has height o bool find (const TreeNode *root, const T& value, int max level) if ( ) return false; if ( return true return
