Given amount of Users and their Codes. Determine which Users are Cheaters while Which are Not Cheaters.↵
↵
User amount <= 10^5, Code Per User <= 10^3.↵
↵
First, if Two Code from Two Different Users is same, Two Users Both are Cheaters.↵
↵
Then, we Iterate All pairs of Users and Iterate All pairs of Codes. If code pair is Same, User Pair are Cheaters.↵
↵
Finally, we Output Those Users who Are Cheaters.↵
↵
Code is below:↵
↵
```python↵
codes = input ("codes")↵
users = input ("users")↵
↵
cheaters = []↵
for u1 in users:↵
for u2 in users:↵
for c1 in codes:↵
for c2 in codes:↵
if c1 == c2 and u1 != u2:↵
cheaters.append(u1)↵
cheaters.append(u2)↵
print (cheaters)↵
```↵
↵
In real Codeforces Might need to get Users and Codes from DataBase.
