Can you try converting this Go code to Python to see if it helps with the
speed?
package main
import (
"bufio"
"fmt"
"os"
)
func build2(a []int) int {
s := []int{0}
for i := 0; i < len(a); i++ {
for j := len(s) - 1; j >= 0; j-- {
if s[j] <= a[i] * 6 {
w := s[j] + a[i]
if j == len(s) - 1 {
s = append(s, w)
} else if s[j+1] > w {
s[j+1] = w
}
}
}
}
return len(s) - 1
}
func main() {
in := bufio.NewReader(os.Stdin)
var T int
fmt.Fscan(in, &T)
for t := 0; t < T; t++ {
var n int
fmt.Fscan(in, &n)
a := make([]int, n)
for i := 0; i < n; i++ {
fmt.Fscan(in, &a[i])
}
res := build2(a)
fmt.Printf("Case #%d: %d\n", t + 1, res)
}
}
