  Jill Rides Again  Jill likes to ride her bicycle, but since the pretty city of Greenhills where she lives has grown, Jill often uses the excellent public bus system for part of her journey. She has a folding bicycle which she carries with her when…

Given a binary tree, find the length of the longest consecutive sequence path. The path refers to any sequence of nodes from some starting node to any node in the tree along the parent-child connections. The longest consecutive path need to be from p…

Given an unsorted array of integers, find the length of the longest consecutive elements sequence. For example, Given [100, 4, 200, 1, 3, 2], The longest consecutive elements sequence is [1, 2, 3, 4]. Return its length: 4. Your algorithm should run i…

题目描述: 给一个浮点数序列,取最大乘积连续子串的值,例如 -2.5,4,0,3,0.5,8,-1,则取出的最大乘积连续子串为3,0.5,8. 也就是说,上述数组中,3 0.5 8这3个数的乘积3*0.5*8=12是最大的,而且是连续的. 算法1: 首先,枚举的话,复杂度是 O(N^2) 算法2:O(N) 首先发现这个题与最长连续子数组的和非常类似. 考虑用 D.P. 来求解. 定义  max_vec[i] ----- 以 a[i] 结尾的子数组的最大乘积 min_vec[i] ------ 以…

最长连续序列 给定一个未排序的整数数组,找出最长连续序列的长度. 说明 要求你的算法复杂度为O(n) 样例 给出数组[100, 4, 200, 1, 3, 2],这个最长的连续序列是 [1, 2, 3, 4],返回所求长度 4 解题 排序后比较简单,快排O(nlogn) 后面只需要O(n)的时间复杂度求解了 发现原数组里面有重复数字的时候,下面方法行不通了. public class Solution { /** * @param nums: A list of integers * @retu…

Given an unsorted array of integers, find the length of longest continuous increasing subsequence. Example 1: Input: [1,3,5,4,7] Output: 3 Explanation: The longest continuous increasing subsequence is [1,3,5], its length is 3. Even though [1,3,5,7] i…

Given a binary array, find the maximum number of consecutive 1s in this array. Example 1: Input: [1,1,0,1,1,1] Output: 3 Explanation: The first two digits or the last three digits are consecutive 1s. The maximum number of consecutive 1s is 3. Note: T…
