示例如下：
package main
import "fmt"
func Versionordinal(version string) string {
// ISO/IEC 14651:2011
const maxByte = 1<<8 - 1
vo := make([]byte,len(version)+8)
j := -1
for i := 0; i < len(version); i++ {
b := version[i]
if '0' > b || b > '9' {
vo = append(vo,b)
j = -1
continue
}
if j == -1 {
vo = append(vo,0x00)
j = len(vo) - 1
}
if vo[j] == 1 && vo[j+1] == '0' {
vo[j+1] = b
continue
}
if vo[j]+1 > maxByte {
panic("Versionordinal: invalid version")
}
vo = append(vo,b)
vo[j]++
}
return string(vo)
}
func main() {
versions := []struct{ a,b string }{
{"1.05.00.0156","1.0.221.9289"},// Go versions
{"1","1.0.1"},{"1.0.1","1.0.2"},{"1.0.2","1.0.3"},{"1.0.3","1.1"},{"1.1","1.1.1"},{"1.1.1","1.1.2"},{"1.1.2","1.2"},}
for _,version := range versions {
a,b := Versionordinal(version.a),Versionordinal(version.b)
switch {
case a > b:
fmt.Println(version.a,">",version.b)
case a < b:
fmt.Println(version.a,"<",version.b)
case a == b:
fmt.Println(version.a,"=",version.b)
}
}
}
运行结果：
1.05.00.0156 > 1.0.221.9289
1 < 1.0.1
1.0.1 < 1.0.2
1.0.2 < 1.0.3
1.0.3 < 1.1
1.1 < 1.1.1
1.1.1 < 1.1.2
1.1.2 < 1.2
