代码如下: 1importjava.util.*;23publicclassSolution {4privatestaticintneed = 0;5privatestaticinthasFound = 0;67privatestaticvoidswap(int[] ar,inti,intj){8inttemp =ar[i];9ar[i]=ar[j];10ar[j]=temp;11}12privatestaticintPartition(int[] ar,intstart,intend){13intpivot =ar[end];14inti ...
Here’s a quick example. Let’s say you wanted to concatenate a string in C#, but you have no idea how. All you would have to do is search the query and hit enter. You’ll immediately get the accurate solution, as well as the opportunity to edit the code right in your search resu...

2 Catch the sparkle: if only one number is duplicated in [1..n], all following numbers will be "shifted" right. classSolution {public:intfindDuplicate(vector<int>&nums) {intnp =nums.size();intn = np -1;ints =1, e =n;while(s<e) ...
classSolution {public:/** * @param A: An integer matrix * @return: The index of the peak*/vector<int> findPeakII(vector<vector<int> >A) {intn =A.size();intm = A[0].size();inti =1, j =1;while(i < m -1&& j < n -1) ...
It is a matter of hashmap use. For the follow-up: typedef unordered_map<int, unsigned>HM;classSolution { HM go(TreeNode*p) {if(!p)returnHM(); auto rl= go(p->left); auto rr= go(p->right); HM r=rl;for(auto &kv : rr) r[kv.first] +=kv.second; ...
* Definition for a binary tree node. * struct TreeNode { * int val; * TreeNode *left; * TreeNode *right; * TreeNode(int x) : val(x), left(NULL), right(NULL) {} * };*/classSolution { vector<vector<int>>ret;intgo(TreeNode *p)//return max height{if(!p)return0;inthl = ...
