For example, if you use string-related functions,import the strutil package like below:\n\n```go\nimport \"github.com\u002Fduke-git\u002Flancet\u002Fv2\u002Fstrutil\"\n```\n\n## Example\n\nHere takes the string function Reverse (reverse order string) as an example, and the strutil package needs to be imported.\n\n```go\npackage main\n\nimport (\n    \"fmt\"\n    \"github.com\u002Fduke-git\u002Flancet\u002Fv2\u002Fstrutil\"\n)\n\nfunc main() {\n    s := \"hello\"\n    rs := strutil.Reverse(s)\n    fmt.Println(rs) \u002F\u002Folleh\n}\n```\n\n## Documentation\n\n### \u003Cspan id=\"index\">Index\u003Cspan>\n\n-   [Algorithm](#user-content-algorithm)\n-   [Compare](#user-content-compare)\n-   [Concurrency](#user-content-concurrency)\n-   [Condition](#user-content-condition)\n-   [Convertor](#user-content-convertor)\n-   [Cryptor](#user-content-cryptor)\n-   [Datetime](#user-content-datetime)\n-   [Datastructure](#user-content-datastructure)\n-   [EventBus](#user-content-eventbus)\n-   [Enum](#user-content-enum)\n-   [Fileutil](#user-content-fileutil)\n-   [Formatter](#user-content-formatter)\n-   [Function](#user-content-function)\n-   [Maputil](#user-content-maputil)\n-   [Mathutil](#user-content-mathutil)\n-   [Netutil](#user-content-netutil)\n-   [Pointer](#user-content-pointer)\n-   [Random](#user-content-random)\n-   [Retry](#user-content-retry)\n-   [Slice](#user-content-slice)\n-   [Stream](#user-content-stream)\n-   [Structs](#user-content-structs)\n-   [Strutil](#user-content-strutil)\n-   [System](#user-content-system)\n-   [Tuple](#user-content-tuple)\n-   [Validator](#user-content-validator)\n-   [Xerror](#user-content-xerror)\n\n\u003Ch3 id=\"algorithm\">1.
