Golang 中的 Strings.TrimLeftFunc()函数，示例为
Original: https://www.geeksforgeeks.org/strings-trimleftfunc-function-in-golang-with-examples/
string。TrimLeftFunc()函数返回字符串 s 的片段，其中删除了满足 f(C)的所有前导 Unicode 代码点 c。
语法：
func TrimLeftFunc(s string, f func(rune) bool) string
这里，s 是字符串，func()是满足字符串字符的方法。
返回值：从字符串中去掉前导字符后返回字符串。
示例 1：
// Golang program to illustrate
// the strings.TrimLeftFunc() Function
package main
// importing fmt, unicode and strings
import (
"fmt"
"strings"
"unicode"
)
// Calling Main method
func main() {
// Here we have a string. The function
// returns true for the letters
// and all other will trim out
// from the string only from Left
fmt.Print(strings.TrimLeftFunc("77GeeksForGeeks!!!", func(r rune) bool {
return !unicode.IsLetter(r)
}))
}
