This solution works only if the array has positive integers and all the elements in the array are in the range from 1 to n. As we know A XOR A = 0. We have n + 2 elements in an array with 2 repeated elements (say repeated elements are X and Y) and we ...
Given an array of integers, 1 ≤ a[i] ≤n(n= size of array), some elements appear twice and others appear once. Find all the elements that appear twice in this array. Could you do it without extra space and in O(n) runtime? Example: Input: [4,3,2,7,8,2,3,1] Output: [2...
Given an array of integers where 1 ≤ a[i] ≤n(n= size of array), some elements appear twice and others appear once. Find all the elements of [1,n] inclusive that do not appear in this array. Could you do it without extra space and in O(n) runtime? You may assume the returne...

438. Find All Anagrams in a String # 题目 # Given a string s and a non-empty string p, find all the start indices of p’s anagrams in s. Strings consists of lowercase English letters only and the length of both strings s and p will not be larger than 2
By default, the find.address method returns the address of the first cell where that information is foundIf the dataset contains repeating values, we won’t get all the cells’ addresses. We may use the Do…Loop statement to get all the cells’ addresses. 2.1. Finding All Cell Addresses ...
We are required to write a JavaScript function that takes in an array of literals, such that some array elements are repeated. We are required to return an array that contains that appear only once (not repeated). For example: If the array is:> const arr = [9, 5, 6, 8, 7, 7, ...
Practice this problem A simple solution would be to store frequencies of the array elements in a count array or a map and print elements with odd frequencies. This approach’s advantage is that it can work on any input range in linear time, but it requires extra space. To solve this prob...
