Arraysare a fundamental way of organizing data in programming that provides a systematic way to store and organize elements of the same data type. What if there are duplicate elements in an array? Without considering duplicates, storing an array of (n) elements requires (O(n)) space, accounti...

Given an array of integers, remove the duplicate numbers in it. Do it in place in the array. Move the unique numbers to the front of the array. Return the total number of the unique numbers. You don't need to keep the original order of the integers. Example 1: Input: nums = [1,...
Contains Duplicate I Given an array of integers, find if the array contains any duplicates. Your function should return true if any value appears at least twice in the array, and it should return false if every element is distinct. 集合法 复杂度 时间O(N) 空间 O(N) 思路 用一个集合记录...

LeetCode Top Interview Questions 217. Contains Duplicate (Java版; Easy) 题目描述 Given an array of integers, find if the array contains any duplicates. Your function should return true if any value appears at least twice in the array, and it should return false if every element is distinct....
Note: You must not modify the array (assume the array is read only). You must use only constant, O(1) extra space. Your runtime complexity should be less than O(n2). There is only one duplicate number in the array, but it could be repeated more than once. ...
There is a small function missing here:create_array_of_unique_values. We can use a hash-table to lookup values we've added already, thus ensuring that we never add a value twice. Example code: defcreate_array_of_unique_values(N):temp={}n=Nwhilen:foriinrange(n):temp[random.randrange...
This results in a set containing three arrays:[A, B, C], [D, E, F], [A, B, C], where the array[A, B, C]is repeated. The task is to remove the duplicate arrays from the set. 1. Use aSet<List> The recommended solution is to useSet<List>instead of aSet<String[]>, which...
Given an array of integers, find out whether there are two distinct indicesiandjin the array such that the absolute difference between nums[i] and nums[j] is at mosttand the absolute difference betweeniandjis at mostk. 找出数组中有没有最多相距k,同时最大相差t的两个数。
