Question
Implement a function duplicate to duplicate an array
As shown below:
For input
arr = [1, 2]
duplicate(arr) should return
[1, 2, 1, 2]
Solution
Sure, here is a simple implementation of the "duplicate" function in Python:
def duplicate(arr):
return arr * 2
This function works by using the list multiplication feature in Python, which repeats the list a specified number of times. In this case, we are repeating the list twice (arr * 2), which effectively duplicates the array.
Here is how you can use this function:
arr = [1, 2]
print(duplicate(arr)) # Output: [1, 2, 1, 2]
This will print [1, 2, 1, 2] as expected.
