I did something similar, every time I tried to print x in the for loop I was getting a vertical output, so I made it a string.

*Edit: I copy and pasted your code, and didn't pass due to having the vertical output. Did it work for you?

This passed for me.

import sys

n = int(input().strip())
arr = [int(arr_temp) for arr_temp in input().strip().split(' ')]

c = ""
for x in arr[::-1]:
    c += str(x) + " "
print(c)
