期望输出和=10 3x2+1x1+1x3=10

更新了前一个的代码。

def findwater(a,n):                     
left = [0]*n                    
right = [0]*n                   
sum = 0                 
left[0] = a[0]          
for i in range(1,n):    
    left[i] = max(left[i-1],a[i])   
right[n-1] = a[n-1]
for i in range((n-2),-1,-1):    
    right[i] = max(right[i+1],a[i])
for i in range(0,n):        
    sum = sum + (min(left[i],right[i])-a[i]*1)      
return sum

a = [3,0,0,2,0,4]   
n = len(a)
print(findwater(a,n))

这次我犯了这个错误 左[I]=最大值(左[I-1],A[I]) 类型错误:“int”对象不可调用 帮助我更正我的代码。
