4. Python program to print the duplicate elements of an array
In this program, we need to print the duplicate elements present in the array. This can be done through two loops. The first loop will select an element and the second loop will iteration through the array by comparing the selected element with other elements. If a match is found, print the duplicate element.
In the above array, the first duplicate will be found at index 4 which is the duplicate of the element (2) present at index 1. So, duplicate elements in the above array are 2, 3 and 8.
Duplicate elements in given array: 2 3 8
