Provide tags and a correct Python 3 solution for this coding contest problem.
Once again, Boris needs the help of Anton in creating a task. This time Anton needs to solve the following problem:

Tags: greedy, implementation
Correct Solution:
```
for _ in range(int(input())):
n = int(input())
a = list(map(int, input().split()))
b = list(map(int, input().split()))
left = set()
res = 'YES'
for i in range(n):
