请教一道Akuna capital OA题 给大家加米！

hmmm 我开始想的不对 是找所有的完全图

1. def angryAnimals(n, a, b):
   
2.     enermy = [-1] * n
   
3.     for i in range(len(a)):
   
4.         x, y = (a[i]-1, b[i]-1) if a[i]<b[i] else (b[i]-1, a[i]-1)
   
5.         enermy[y] = max(enermy[y], x)
   
6.     left, result = 0, 0
   
7.     for i in range(n):
   
8.         left = max(enermy[i] + 1, left)
   
9.         result += i - left + 1
   
10.     return result
    
11. print(angryAnimals(3, [1,2,3], [3,3,1]))
