For problem statement at 0-999/100-199/170-179/175/problemD.txt this is a correct solution, but verifier at 0-999/100-199/170-179/175/verifierD.go ends with case 32 failed: expected -0.000000 got 0.000000
exit status 1 can you fix the verifier? ```go
package main

import (
	"fmt"
)

func getS(hp, l, r, p int) []float64 {
	if p == 100 {
		return nil
	}
	dp := make([]float64, hp)
	dp[0] = 1.0
	S := make([]float64, 0, 20000)
	S = append(S, 1.0)

	probMiss := float64(p) / 100.0
	probHit := 1.0 - probMiss
	probEach := probHit / float64(r-l+1)

	sumDp := make([]float64, hp+1)

	for k := 1; ; k++ {

				val += (sumDp[maxY+1] - sumDp[minY]) * probEach

			currentS += val

	return S
