Given an array of integers sorted in ascending order, find the starting and ending position of a given target value. Your algorithm's runtime complexity must be in the order of O(log n). If the target is not found in the array, return [-1, -1]. For e
Given an unsorted array, find the maximum difference between the successive elements in its sorted form. Try to solve it in linear time/space. Return 0 if the array contains less than 2 elements. You may assume all elements in the array are non-negat

Given an array of numbers nums, in which exactly two elements appear only once and all the other elements appear exactly twice. Find the two elements that appear only once.For example:Given nums = [1, 2, 1, 3, 2, 5], return [3, 5].Note:1.The order of
题1. 给定一个无符号整型数据(unsigned int),找出其对应二进制数据中bit位为1的最高/低索引. 比如:对于数据0,返回0:数据1,返回1:数据0x80000000,返回32: 题2. 给定一个无符号64bit整型数据(unsigned long long int),找出其对应二进制数据中bit位为1的最高/低索引. 比如:对于数据0,返回0:数据1,返回1:数据0x4000000000000000,返回63: 题3. 给定一个无符号长整型数据(unsigned long i
题目: Create a method that takes an array/list as an input, and outputs the index at which the sole odd number is located. This method should work with arrays with negative numbers. If there are no odd numbers in the array, then the method should outpu

Median is the middle value in an ordered integer list. If the size of the list is even, there is no middle value. So the median is the mean of the two middle value. Examples: [2,3,4] , the median is 3 [2,3], the median is (2 + 3) / 2 = 2.5 Design a d
