Design a class to find the kth largest element in a stream. Note that it is the kth largest element in the sorted order, not the kth distinct element. Your KthLargest class will have a construc
Explanation: The first two digits or the last three digits are consecutive 1s.The maximum number of consecutive 1s is 3. Note: The input array will only contain 0 and 1. The length of input array is a positive integer and will not exceed 10,000 1. 2. 题意:根据所给的二进制数组(数组...

(mid, right)). If the second max elements in the entire array and the second max element in the 2nd half of the array are equal (i.e.smax_all == smax_2nd), then the maximum element in the array must be in the second half, hence replace theleftpointer with themid...
If we consider the smallest max as a monotonic sequence, the lower bound of the sequence is the largest element in the array, and the higher bound is the sum of all elements. Then we choose the possible “smallest max” at the middle of the sequence and always greedily drops half of of...

Given an index in the array representing a vertex, the index of a vertex's parent or child is calculated through bitwise operations on the binary representation of its index. Each element of the array contains the pre-calculated sum of a range of values, and by combining that sum with ...
https://leetcode.com/problems/max-chunks-to-make-sorted/ 解题方法: Let's say there is en element A[i] in our array. And A[i] != i (because this might be an unsorted array). So in order to make this array sorted, we at least need to sort range from min(i, A[i]) to max...
