To solve this problem, we can follow these steps:

1. Read the number of test cases from the input.
2. Iterate over each test case.
3. Read the input string for the current test case.
4. Initialize a variable `first_char` with the first character of the input string.
5. Initialize an empty string `result` to store the modified string.
6. Iterate over each character in the input string.
7. If the current character is equal to `first_char` and it is not the first occurrence, replace it with '$' and append it to `result`.
8. If the current character is not equal to `first_char` or it is the first occurrence, append it to `result` as it is.
9. Print the `result` string as the output for the current test case.
10. Repeat steps 3-9 for each test case.

Here is the code in Python:

```python
# Step 1
num_test_cases = int(input())

# Step 2
for _ in range(num_test_cases):
# Step 3
input_string = input()

# Step 4
first_char = input_string[0]

# Step 5
result = ""

# Step 6
for i, char in enumerate(input_string):
# Step 7
if char == first_char and i != 0:
result += "$"
# Step 8
else:
result += char

# Step 9
print(result)
```

This program takes the number of test cases as input, followed by the input strings for each test case. It then modifies each input string according to the given condition and prints the modified strings as the output.
