This question is a fill-in-the-blank question. After calculating the result, use the output statement in the code to output the filled result.
As a basketball coach, you'll need to select one player from the following list from positions 11 to 55 to form the team's starting lineup.
The ratings for each player from 11 to 55 are shown in the table below. Can you calculate the maximum possible sum of the ratings of the starting lineup's No. 11 to No. 55?

num1=[97,92,0,0,89,82,0,0,0,95,0,0,94,0,0,0,98,93,0,0]
num2=[90,85,0,0,83,86,0,97,0,99,0,0,91,83,0,0,83,87,0,99]
num3=[0,96,0,0,97,0,0,96,89,0,96,0,0,87,98,0,99,92,0,96]
num4=[0,0,0,80,0,0,87,0,0,0,97,93,0,0,97,93,98,96,89,95]
num5=[0,0,93,86,0,0,90,0,0,0,0,98,0,0,98,86,81,98,92,81]
res=[]
for a in range(20):
    ans=0
    ans+=num1[a]
    for b in range(a+1,20):
        ans+=num2[b]
        for c in range(b+1,20):
            ans+=num3[c]
            for d in range(c+1,20):
                ans+=num4[d]
                for e in range(d+1,20):
                    ans+=num5[e]
                    res.append(ans)
                    ans-=num5[e]
                ans-=num4[d]
            ans-=num3[c]
        ans-=num2[b]
print(max(res))#结果为490
