Merge Two Arrays

Merge two arrays into one.

IntermediatePhase 4 - Level 4: Aggregation & ComparisonExample 3 of 10

1# Take first array
2n1 = int(input("Enter size of first array: "))
3arr1 = []
4for i in range(n1):
5    arr1.append(int(input(f"Array1 element {i+1}: ")))
6

7# Take second array
8n2 = int(input("Enter size of second array: "))
9arr2 = []
10for i in range(n2):
11    arr2.append(int(input(f"Array2 element {i+1}: ")))
12

13# Merge
14merged = arr1 + arr2
15print(f"Merged array: {merged}")

Output

Enter size of first array: 3
Array1 element 1: 1
Array1 element 2: 2
Array1 element 3: 3
Enter size of second array: 2
Array2 element 1: 4
Array2 element 2: 5
Merged array: [1, 2, 3, 4, 5]
