Question
roblem statementGinny, an inquisitive mind fascinated by the intricacies of arrays, has posed a challenge for you. She needs a program that can identify and display the unique elements present in an array. Write a program that includes a function named findUniqueElements where the array is passed as an argument.Input format :The first line of input is an integer value 'N', representing the size of the array.The second line of input consists of N space-separated integers arr[i], representing the elements of the array.Output format :The output displays the integers, representing the unique elements identified within the array, separated by spaces.
Solution
Sure, here is a Python solution for the problem:
def findUniqueElements(arr):
# Create an empty dictionary
unique_elements = {}
# Iterate over each element in the array
for element in arr:
# If the element is not in the dictionary, add it
if element not in unique_elements:
unique_elements[element] = 1
# Return the unique elements
return list(unique_elements.keys())
# Test the function
N = int(input())
arr = list(map(int, input().split()))
print(*findUniqueElements(arr))
This program works by creating an empty dictionary and then iterating over each element in the array. If the element is not already in the dictionary, it is added. The keys of the dictionary are then returned as a list, which represents the unique elements in the array.

Problem Statement You are given a function, int ElementsAndIndices(int arr[], int n); The function takes an integer array 'arr' of size 'n' as its arguments. Implement the function to find and return the number of array elements which are equal to their index value in array i.e. arr[k] = k, 0 <= k < n. Note: Indexing starts from 0. Return -1 if 'arr' is empty or None in case of python Example: Input: 10 1 12 3 5 8 9 7 12 23 Output: 3 Explanation: Index Element 0 10 1 1 2 12 3 3 4 5 5 8 6 9 7 7 8 12 9 23 Elements at index {1, 3, 7} are equal to their index values {1, 3, 7} respectively. Since, these are 3 elements, thus, output is 3. The custom input format for the above case: 10 10 1 12 3 5 8 9 7 12 23 (The first line represents the size of the array, the second line represents the elements of the array) Sample input -3 0 1 3 5 7 Sample Output 1 The custom input format for the above case: 6 -3 0 1 3 5 7 (The first line represents the size of the array, the second line represents the elements of the array) Instructions : This is a template based question, DO NOT write the "main" function. Your code is judged by an automated system, do not write any additional welcome/greeting messages. "Save and Test" only checks for basic test cases, more rigorous cases will be used to judge your code while scoring. Additional score will be given for writing optimized code both in terms of memory and execution time.
