The time complexity of the above solution is O n and requires O n extra space for Map data structure where n is the length of the array 2 Using Array Indices Since all of the array s elements lie within the range 1 n we can check for duplicate elements by marking array elements as negative using the array index as a key For each element in the array nums i invert the sign of the Find all duplicate elements in a limited range array. To use this to solve the original problem do the following First XOR together all the numbers in the list This gives the XOR of all numbers that appear an odd number of times which ends up being all the numbers from 1 to n 1 except the duplicate Now XOR this value with the XOR of all the numbers from 1 to n 1 Given an array a of size N which contains elements from 0 to N 1 you need to find all the elements occurring more than once in the given array Return the answer in ascending order If no such element is found return list containing 1 Note The extra space is only for the array to be returned Try and perform all operations within the provided array
