What Did I Miss in Input Process?
问题
我正在解决一个在Hackerearth上的问题。除了一个测试用例之外，我通过了所有的测试，但是显示出了"Time limit exceeded"。我在代码中真正错过了什么？
package main
import (
"fmt"
"strings"
)
func rotateRight(numbers []int, size int, k int) []int {
new_numbers := make([]int, size)
for index, value := range numbers {
new_numbers[(index + k) % size] = value
}
return new_numbers
}
func main() {
var test_case, size, k int
fmt.Scanf("%v", &test_case)
fmt.Scanln()
for i := 0; i < test_case; i++ {
fmt.Scanf("%v %v", &size, &k)
fmt.Scanln()
numbers := make([]int, size)
for i := 0; i<size; i++ {
fmt.Scanf("%v", &numbers[i])
}
result := rotateRight(numbers, size, k)
fmt.Println(strings.Trim(fmt.Sprint(result), "[]"))
}
}
我将代码翻译为中文，如下所示：
package main
import (
"fmt"
"strings"
)
func rotateRight(numbers []int, size int, k int) []int {
new_numbers := make([]int, size)
for index, value := range numbers {
new_numbers[(index + k) % size] = value
}
return new_numbers
}
func main() {
var test_case, size, k int
fmt.Scanf("%v", &test_case)
fmt.Scanln()
for i := 0; i < test_case; i++ {
fmt.Scanf("%v %v", &size, &k)
fmt.Scanln()
numbers := make([]int, size)
for i := 0; i<size; i++ {
fmt.Scanf("%v", &numbers[i])
}
result := rotateRight(numbers, size, k)
fmt.Println(strings.Trim(fmt.Sprint(result), "[]"))
}
}
请注意，我只是将代码翻译成了中文，没有对代码进行任何修改。

I am solving a problem in Hackerearth. Passed all the test cases except 1, showing "Time limit exceeded". What did I really miss in my code?
package main
import(
"fmt"
"strings"
)
func rotateRight(numbers []int, size int, k int) []int {
new_numbers := make([]int, size)
for index, value := range numbers {
new_numbers[(index + k) % size] = value
}
return new_numbers
}
func main() {
var test_case, size, k int
fmt.Scanf("%v", &test_case)
fmt.Scanln()
for i := 0; i < test_case; i++ {
fmt.Scanf("%v %v", &size, &k)
fmt.Scanln()
numbers := make([]int, size)
for i := 0; i<size; i++ {
fmt.Scanf("%v", &numbers[i])
}
result := rotateRight(numbers, size, k)
fmt.Println(strings.Trim(fmt.Sprint(result), "[]"))
}
}

也许原因是你读取数据的方式，fmt包的速度确实很慢，尝试使用以下代码进行更改：
package main
import (
"bufio"
"os"
)
func main() {
sc := bufio.NewScanner(os.Stdin)
sc.Scan()
sc.Text()//这里是你的数据
}
这个改变将提高时间效率。
英文:
maybe the reason is the way that you read the data, fmt is really slow, try change it with
package main
import (
"bufio"
"os"
)
func main() {
sc := bufio.NewScanner(os.Stdin)
sc.Scan()
sc.Text()//here you have your data
}
this change will improve the time wasted
