print("Original array:")
print(nums)
print("\nNew array after swapping first and last columns of the said array:")

print(new_nums)
Sample Output:
Original array:
[[ 0 1 2 3]
[ 4 5 6 7]
[ 8 9 10 11]
[12 13 14 15]]
New array after swapping first and last columns of the said array:
[[ 3 2 1 0]
[ 7 6 5 4]
[11 10 9 8]
[15 14 13 12]
