栈的部分解答有误

[字符串解码](https://leetcode.cn/problems/decode-string/)

通过此rep的模版无法通过，具体算法如下：
```
func decodeString(s string) string {
if len(s) == 0 {
return ""
}
stack := make([]byte, 0)
for i := 0; i < len(s); i++ {
switch s[i] {
case ']':
temp := make([]byte, 0)
for len(stack) != 0 && stack[len(stack)-1] != '[' {
v := stack[len(stack)-1]
stack = stack[:len(stack)-1]
temp = append(temp, v)
}
// pop '['
stack = stack[:len(stack)-1]
// pop num
idx := 1
for len(stack) >= idx && stack[len(stack)-idx] >= '0' && stack[len(stack)-idx] <= '9' {
idx++
}
// 注意索引边界
num := stack[len(stack)-idx+1:]
stack = stack[:len(stack)-idx+1]
count, _ := strconv.Atoi(string(num))
for j := 0; j < count; j++ {
// 把字符正向放回到栈里面
for j := len(temp) - 1; j >= 0; j-- {
stack = append(stack, temp[j])
}
}
default:
stack = append(stack, s[i])

}
}
return string(stack)
}
```

Start with the repository's stack solution for the linked 字符串解码 problem and compare it with the failing behavior described in the issue. Use the linked LeetCode problem to verify the correction; done means the repository's template produces accepted results for that problem.
