Question
Emma maintains a grocery list on her phone to keep track of the items she needs to buy. However, sometimes she accidentally adds the same item multiple times. To avoid buying duplicates, she wants a program that can remove any duplicate items from her list, ensuring that each item appears only once.Write a program to help Emma clean up her grocery list by removing duplicate items.Input format :The first line consists of an integer N, representing the number of items on Emma's grocery list.The second line consists of an array of integers of size N, where each integer represents a unique code for each grocery item.Output format :The output displays the list of integers representing the unique item codes from Emma's grocery list, with duplicates removed.
Solution
Sure, here is a Python program that can help Emma clean up her grocery list by removing duplicate items.
def remove_duplicates(grocery_list):
# Using set() function to remove duplicates
unique_grocery_list = list(set(grocery_list))
return unique_grocery_list
# Input number of items
N = int(input("Enter the number of items on the grocery list: "))
# Input item codes
grocery_list = []
for i in range(N):
item = int(input("Enter the unique code for item " + str(i+1) + ": "))
grocery_list.append(item)
# Remove duplicates
unique_grocery_list = remove_duplicates(grocery_list)
# Output unique item codes
print("The unique item codes from the grocery list are: ")
for item in unique_grocery_list:
print(item)
This program works by first taking the number of items on the grocery list as input. Then it takes each item code as input and adds it to the grocery list. The remove_duplicates function uses the set() function to remove any duplicate items from the list. Finally, the program prints out the unique item codes.

Problem StatementArun is given an array of integers where all elements appear twice, except for one element that appears only once. The goal is to find this single, non-duplicate element using a linear search algorithm. If the element is not found, print the appropriate message.Assist Arun in solving this challenge.Input format :The first line of input consists of an integer N, representing the number of elements in the array.The second line consists of N space-separated integers, representing the array elements.Output format :The output prints an integer, representing the single non-duplicate element in the given array.If no such element is found, print "No non-duplicate element found".Refer to the sample output for formatting specifications.Code constraints :1 ≤ N ≤ 151 ≤ elements of the array ≤ 30Sample test cases :Input 1 :91 1 2 3 3 4 4 8 8Output 1 :2Input 2 :712 16 12 15 17 16 15Output 2 :17Input 3 :414 26 14 26Output 3 :No non-duplicate element found
Problem StatementYou wish to help Ashish, who possesses a collection of N strings, some of which may be duplicated, and has been assigned the task of finding the kth unique string.If the number of unique strings is less than k, he needs to display an empty string. Considering you are Ashish's best friend can you assist him with this challenge?Input FormatThe first line contains an integer N denoting the number of strings.The next N lines contain strings.The next line contains an integer k.Output FormatThe output contains the kth distinct string. If there are less than k unique string display an empty string.Constraints1<=N<=105-10^8<=arr[i].length()<=10^8Sample Testcase 0Testcase Input6dbcbca2Testcase OutputaExplanationThe only strings in arr that are distinct are "d" and "a." The letter "d" comes first, making it the first separate string.Because "a" appears second, it is the second distinct string. "a" is returned since k == 2.
