Find All Duplicates in an Array Given an integer array nums of length n where all the integers of nums are in the range 1 n and each integer appears once or twice return an array of all the integers that appears twice You must write an algorithm that runs in O n time and uses only constant extra space Simple Approach The idea is to use nested loop and for each element check if the element is present in the array more than once or not If present then store it in a Hash map Otherwise continue checking other elements Below is the implementation of the above approach C Java Python3 C Javascript include bits stdc h using namespace std
