英文:
Iterate over two strings at the same time
问题
我只是想知道是否有一种优雅的方法可以同时迭代两个字符串：
var ascii_runes = []rune(string_1)
var shifted_runes = []rune(string_2)
for i := 0; i < len(string_1); i++ {
fmt.Println(string(ascii_runes[i]) + string(shifted_runes[i]))
}
英文:
I am just wondering if there is any beautiful way to iterate over two strings at the same time:
var ascii_runes = []rune(string_1)
var shifted_runes = []rune(string_2)
for i := 0; i < len(string_1); i++ {
fmt.Println(string(ascii_runes[i]) + string(shifted_runes[i]))
}

不确定我是否理解正确，但是举个例子：
package main
import (
"fmt"
)
var (
ascii = []rune("string1")
shifted = []rune("STRING!")
)
func main() {
for i, v := range ascii {
fmt.Printf("%c%c\n", v, shifted[i])
}
}
也可以在这里查看：http://play.golang.org/p/2ruvLFg_qe
输出：
sS
tT
rR
iI
nN
gG
1!
英文:
Not sure IIUC, but for example:
package main
import (
"fmt"
)
var (
ascii = []rune("string1")
shifted = []rune("STRING!")
)
func main() {
for i, v := range ascii {
fmt.Printf("%c%c\n", v, shifted[i])
}
}
Also here: http://play.golang.org/p/2ruvLFg_qe
Output:
sS
tT
rR
iI
nN
gG
1!

例如，
package main
import "fmt"
func main() {
var runes_1, runes_2 = []rune("string_1"), []rune("string_2")
for i := 0; i < len(runes_1) && i < len(runes_2); i++ {
fmt.Println(string(runes_1[i]) + string(runes_2[i]))
}
}
输出：
ss
tt
rr
ii
nn
gg
__
12
英文:
For example,
package main
import "fmt"
func main() {
var runes_1, runes_2 = []rune("string_1"), []rune("string_2")
for i := 0; i < len(runes_1) && i < len(runes_2); i++ {
fmt.Println(string(runes_1[i]) + string(runes_2[i]))
}
}
Output:
ss
tt
rr
ii
nn
gg
__

不是特别漂亮，但是一种高效的方法是使用strings.NewReader和它的ReadRune方法。
func Less(s1, s2 string) bool {
rdr1 := strings.NewReader(s1)
rdr2 := strings.NewReader(s2)
for {
rune1, _, err1 := rdr1.ReadRune()
rune2, _, err2 := rdr2.ReadRune()
if err2 == io.EOF { return false }
if err1 == io.EOF { return true }
if rune1 != rune2 { return rune1 < rune2 }
}
}
英文:
Not particularly beautiful, but an efficient way is to use strings.NewReader and its ReadRune method.
func Less(s1, s2 string) bool {
rdr1 := strings.NewReader(s1)
rdr2 := strings.NewReader(s2)
for {
rune1, _, err1 := rdr1.ReadRune()
rune2, _, err2 := rdr2.ReadRune()
if err2 == io.EOF { return false }
if err1 == io.EOF { return true }
if rune1 != rune2 { return rune1 < rune2 }
}
}
