Proposed solution

Looking at this problem, I need to:

1. Read the number of test cases
2. For each test case, read a string that ends with "us"
3. Convert it to plural form by replacing "us" with "i"

Let me trace through the examples:
- "us" → "i" (remove "us", add "i")
- "sus" → "si" (remove "us", add "i") 
- "fungus" → "fungi" (remove "us", add "i")
- "cactus" → "cacti" (remove "us", add "i")

The pattern is: take the string and replace the last 2 characters ("us") with "i".

```python
t = int(input())
for _ in range(t):
    w = input().strip()
    # Replace "us" at the end with "i"
    plural = w[:-2] + "i"
    print(plural)
```

Test output (stdout)
