Time limit exceeded but code is the most efficient it can be AND linear. (INTEST)

package main
import (
“fmt”
)

func main() {
	var n, k, t, i, count int
	fmt.Scanln(&n, &k)
	for i = 0; i < n; i++ {
		fmt.Scanln(&t)
		if t % k == 0 {
			count++
		}
	}
	fmt.Println(count)
}

Why is this simple linear efficient code exceeding the 8 second time limit?
