Question
Given 2 arrays A and B of size N and M respectively. You have to find the number of elements in the union and intersection between both the arrays.Note that both the arrays contain distinct elements.Input FormatFirst line of input contains N - size of the array A. The next line contains the N integers of array A. The next line of input contains M - size of the array B. The next line contains the M integers of array B.Output FormatPrint the count of number of elements in union and intersection separated by space.Constraints
Solution
To solve this problem, you can follow these steps:
- Read the size of the arrays A and B. Let's denote them as N and M respectively.
- Read the elements of array A and array B.
- Create a set for each array. In Python, you can use the set() function to do this. This will remove any duplicate elements in the arrays.
- Find the union of the two sets. In Python, you can use the union() function to do this. The union of two sets is a set of all distinct elements from both the sets.
- Find the intersection of the two sets. In Python, you can use the intersection() function to do this. The intersection of two sets is a set of elements that are common to both the sets.
- Print the size of the union set and the intersection set. In Python, you can use the len() function to find the size of a set.
Here is a Python code snippet that implements these steps:
# Read the size of the arrays
N = int(input())
M = int(input())
# Read the elements of the arrays
A = list(map(int, input().split()))
B = list(map(int, input().split()))
# Create sets from the arrays
set_A = set(A)
set_B = set(B)
# Find the union and intersection of the sets
union_set = set_A.union(set_B)
intersection_set = set_A.intersection(set_B)
# Print the size of the union and intersection sets
print(len(union_set), len(intersection_set))
This code will print the number of elements in the union and intersection of the two arrays, separated by a space.
