For problem statement at 0-999/700-799/780-789/784/problemG.txt this is a correct solution, but verifier at 0-999/700-799/780-789/784/verifierG.go ends with case 1 failed: expected ++++++++++++++++++++++++++++++++++++++++++++++++. got ++++++++++++++++++++++++++++++++++++++++++++++++++.>+++++++++++++++++++++++++++++++++++++++++++++++++++.>+++++++++++++++++++++++++++++++++++++++++++++++++++++++++.>
exit status 1 can you fix the verifier? ```go
package main
import (
"fmt"
"io"
"os"
"strings"
)
func main() {
input, err := io.ReadAll(os.Stdin)
if err != nil {
return
}

// Filter out any whitespace or unwanted characters from the input
var expr string
for _, c := range s {
if (c >= '0' && c <= '9') || c == '+' || c == '-' {
expr += string(c)
}
}
if len(expr) == 0 {
return
}
var result int
var currentNum int
var currentOp byte = '+'
// Parse and evaluate the arithmetic expression
for i := 0; i < len(expr); i++ {
c := expr[i]

currentOp = c
currentNum = 0
}
}
// Apply the final operand
if currentOp == '+' {
result += currentNum

// Although the problem states the final result is in [0, 255],
// applying 8-bit unsigned wrap-around is a safe measure.
result = ((result % 256) + 256) % 256
// Convert the evaluated result to a string
resStr := fmt.Sprintf("%d", result)
// Generate Brainfuck code
// Since Brainfuck doesn't accept input here (no ',' command support needed),
// our generator will write code that simply outputs the result characters.
var bf strings.Builder
for i := 0; i < len(resStr); i++ {
// Output '+' equal to the ASCII value of the character
bf.WriteString(strings.Repeat("+", int(resStr[i])))
// Print the character and move to the next memory cell
bf.WriteString(".>")
}
// Print the generated Brainfuck program to standard output
fmt.Print(bf.String())
