Test Case Generator
Certainly! It looks like your problem statement got cut off. However, I can help you create a test case generator based on a common scenario in competitive programming involving grids, paths, and bombs.
Here’s a complete problem statement based on what you've provided and a test case generator for it:
### Problem Statement: Bomb Removal
**Description**
There are \( N \) fuse cords and bombs, each with one bomb, on a grid of height \( H \) and width \( W \). Each fuse cord and bomb are placed on a path consisting of \( L_i \) squares, with the \( j \)-th square of the path specified by coordinates \( (px_{ij}, py_{ij}) \). Each bomb is located at the last square of its path \( (px_{iL_i}, py_{iL_i}) \).
**Input**
1. Two integers \( H \) and \( W \) (1 ≤ \( H, W \) ≤ 1000), representing the height and width of the grid.
2. An integer \( N \) (1 ≤ \( N \) ≤ 100), representing the number of fuse cords.
3. For each fuse cord:
- An integer \( L_i \) (1 ≤ \( L_i \) ≤ 100), representing the length of the path of the \( i \)-th fuse cord.
- \( L_i \) pairs of integers \( (px_{ij}, py_{ij}) \) (1 ≤ \( px_{ij} \) ≤ \( H \), 1 ≤ \( py_{ij} \) ≤ \( W \)), representing the coordinates of the path for the \( i \)-th fuse cord.
**Output**
Print the grid after all bombs have been placed.
**Example**

```
In the example, there are 2 fuse cords with bombs. The first fuse cord has a path of length 3 ending at (3,3), and the second fuse cord has a path of length 2 ending at (5,5). Bombs are placed at these positions on the grid.
### Test Case Generator
Here is a Python function to automatically generate test cases for the problem:
```python
import random
def generate_path(H, W, L):
path = []
for _ in range(L):
x = random.randint(1, H)
y = random.randint(1, W)
path.append((x, y))
return path
def tcgen():
H = random.randint(1, 1000)
W = random.randint(1, 1000)
N = random.randint(1, 100)
test_case = []
test_case.append(f"{H} {W}")
test_case.append(f"{N}")
for _ in range(N):
L = random.randint(1, 100)
path = generate_path(H, W, L)
path_str = ' '.join(f"{x} {y}" for (x, y) in path)
test_case.append(f"{L} {path_str}")
return '\n'.join(test_case)
# Example usage
print(tcgen())
```
This function generates a random grid height and width, a random number of fuse cords, and for each fuse cord, it generates a random path of specified length within the grid. The output is formatted as a string that matches the input specification of the problem.
