剑指上用了指针传递,这里用的引用传递
class Solution { public: bool IsBalanced_Solution(TreeNode* pRoot) { int depth = 0; return IsBalanced(pRoot,depth); } bool IsBalanced(TreeNode* pRoot,int& depth){ if(pRoot == NULL){ depth = 0; return true; } int left = 0; int right = 0; if(IsBalanced(pRoot->left,left) && IsBalanced(pRoot->right,right)){ int diff = left - right; if(diff <= 1 && diff >= -1){ depth = 1 + (left > right ? left : right); return true; } } return false; } };
