题目：Simplify Path

Given an absolute path for a file (Unix-style), simplify it. Or in other words, convert it to the canonical path.

给一个文件的绝对路径，转换成合法的简单路径

思路

简单粗暴

code

func simplifyPath(path string) string {
dirs := strings.FieldsFunc(path, func(s rune) bool {
if s == '/' {
return true
}
return false
})
for i := 0; i < len(dirs); i++ {
if dirs[i] == "." {
dirs = append(dirs[:i], dirs[i+1:]...)
i--
} else {
if dirs[i] == ".." {
if i == 0 {
dirs = dirs[1:]
i--
continue
}
dirs = append(dirs[:i-1], dirs[i+1:]...)
i -= 2
}
}
}
res := "/"
for i := 0; i < len(dirs); i++ {
res += dirs[i]
if i != len(dirs)-1 {
res += "/"
}
}
return res
}
