Dec 14, 2023 · Given an array arr of N elements, the task is to find the length of the smallest subarray of the given array that contains at least one duplicate element. A subarray is formed from consecutive elements of an array.
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.
May 7, 2024 · Given an array of n elements containing elements from 0 to n-1, with any of these numbers appearing any number of times, find these repeating numbers in O(n) and using only constant memory space. Example: Input: n = 7 , array = {1, 2, 3, 1, 3, 6, 6} Output: 1, 3 and 6. Explanation: Duplicate element in the array are 1 , 3 and 6 Input: n = 6, array
Given an array arr of size n which contains elements in range 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
Find the Duplicate Number - Given an array of integers nums containing n + 1 integers where each integer is in the range [1, n] inclusive. There is only one repeated number in nums, return this repeated number.
The most basic way to find duplicate elements in an array is by using a nested for loops. For each element in the array, check if it is present in the rest of the array or not, if it is present, then increment the count of duplicates by 1.

Jul 18, 2012 · Suppose I have an array. a = np.array([1, 2, 1, 3, 3, 3, 0]) How can I (efficiently, Pythonically) find which elements of a are duplicates (i.e., non-unique values)? In this case the result would be array([1, 3, 3]) or possibly array([1, 3]) if efficient. I've come up with a few methods that appear to work: Masking
