LeetCode中，如果输入的是一组数，往往函数的参数是一个vector，自己再写一个读入转成vector难免有些难...
方案一:先通过二分查找,找到目标值target在数组中的位置mid,然后以mid为中心,向两边依次查找是否有与target相同的数组元素 1publicclassSolution {2publicint[] searchRange(int[] nums,inttarget) {3if(nums ==null|| nums.length == 0)returnnewint[] {-1, -1};4if(nums.length == 1)returnnums[0]...

【面试训练】leetcode42. 给定 n 个非负整数表示每个宽度为 1 的柱子的高度图,计算按此排列的柱子,下雨之后能接多少雨水。思路:挨个看每个节点能存的水,相加起来即是结果;每个节点能接的水=min(左边的最高,右边最高) - 节点高度class Solution {public: int trap(vector<int>& height) { int res = 0; ...
class Solution { public: bool isMatch(const char *s, const char *p) { // IMPORTANT: Please reset any member data you declared, as // the same Solution instance will be reused for each test case. bool star = false, staremerge = false; ...
//decompose the big problem into smaller problem private: vector<bool> numT;//keep record of number state, choosen or not vector<int> factT;//save factorial number public: string getPermutation(int n, int k) { // Start typing your C/C++ solution below ...

The Python editorial for both the BFS and DFS solutions of this question are missing the "class Solution" part of the code. This generates a SynthaxError when testing the codes. Language Used for Code None Code used for Submit/Run operation ...
public class Solution { public bool IsPalindrome(int x) { // 特殊情况: // 如上所述,当 x < 0 时,x 不是回文数。 // 同样地,如果数字的最后一位是 0,为了使该数字为回文, // 则其第一位数字也应该是 0 // 只有 0 满足这一属性 if(x < 0 || (x % 10 == 0 && x != 0)) { ...
