题目如下: 解题思路:题目要求的是在数组中找到一个下标最小的index,使得index左边(包括自己)子序列的最大值小于或者等于右边序列的最小值.那么我们可以先把数组从最左边开始到数组最右边所有子序列的最大值都求出来存入leftMax数组,同时也把从数组最右边开始到最左边的所有子序列的最小值求出来存入rightMin数组,最后找出最小的i使得leftMax[i] <= rightMin[i+1]即可. 代码如下: class Solution(object): def partitionDisj…

Assume you have k<=10^5 intervals [a_i, b_i] \in [1,10^18] (some of them may overlap), and you need to choose a set of intervals mutually disjoint such that their union is maximal. Not maximum number of disjoint intervals, but the union must cover th…

Given a data stream input of non-negative integers a1, a2, ..., an, ..., summarize the numbers seen so far as a list of disjoint intervals. For example, suppose the integers from the data stream are 1, 3, 7, 2, 6, ..., then the summary will be: [1, 1…
