For problem statement at 1000-1999/1500-1599/1570-1579/1579/problemC.txt this is a correct solution, but verifier at 1000-1999/1500-1599/1570-1579/1579/verifierC.go ends with case 1 failed
input:
1
3 18 2
.*...*******.*...*
.......*..*.......
..*....*.*.***....
expected:
NO
but got:

exit status 1 can you fix the verifier? ```go
package main

import "fmt"

func solve() {
    var n, m, k int
    fmt.Scan(&n, &m, &k)
    
    grid := make([]string, n)
    for i := 0; i < n; i++ {
        fmt.Scan(&grid[i])
    }
    
    covered := make([][]bool, n)
    for i := 0; i < n; i++ {
        covered[i] = make([]bool, m)
    }
    
    _ = k
    _ = covered
    _ = grid
}

func main() {
    solve()
}
```
