将按数组 [2] <-> 数组 [3]、数组 [1] <-> 数组 [4] 和数组 [0] <-> 数组 [5] 的顺序进行]。
package main
import (
"fmt"
)
func main() {
a := []int{1, 2, 3, 4, 5, 6, 7}
reverseArray := ReverseSlice(a)
fmt.Println("反转后 : ", reverseArray)
}
func ReverseSlice(a []int) []int {
for i := len(a)/2 - 1; i >= 0; i-- {
pos := len(a) - 1 - i
a[i], a[pos] = a[pos], a[i]
}
return a
}
7、将切片转换为某个分隔符分隔的字符串
package main
import (
"fmt"
"strconv"
"strings"
)
func main() {
result := ConvertSliceToString("&", []int{10, 20, 30, 40})
fmt.Println("Slice converted string : ", result)
}
func ConvertSliceToString(separator string, input []int) string {
var output []string
for _, i := range input {
output = append(output, strconv.Itoa(i))
}
return strings.Join(output, separator)
}
8、将给定的字符串转换为snake_case
package main
import (
"fmt"
"regexp"
"strings"
)
func main() {
snakeCase := ConvertToSnakeCase("ILikeProgrammingINGo")
fmt.Println("String in snake case : ", snakeCase)
}
func ConvertToSnakeCase(input string) string {
var matchChars = regexp.MustCompile("(.)([A-Z][a-z]+)")
var matchAlpha = regexp.MustCompile("([a-z0-9])([A-Z])")
snake := matchChars.ReplaceAllString(input, "${1}_${2}")
snake = matchAlpha.ReplaceAllString(snake, "${1}_${2}")
return strings.ToLower(snake)
}
