Find duplicates in a given array when elements are not limited to a
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
Remove duplicates from unsorted array using Map data structure, Given an unsorted array of integers print the array after removing the duplicate elements from it We need to print distinct array elements according to their first occurrence Examples Input arr 1 2 5 1 7 2 4 2 Output 1 2 5 7 4 Explanation 1 2 appear more than one time Approach
