Two arrays are called similar if one can be obtained from another by swapping at most one pair of elements in one of the arrays.

Given two arrays a and b, check whether they are similar.

Example

• For a = [1, 2, 3] and b = [1, 2, 3], the output should be
  areSimilar(a, b) = true.

  The arrays are equal, no need to swap any elements.

• For a = [1, 2, 3] and b = [2, 1, 3], the output should be
  areSimilar(a, b) = true.

  We can obtain b from a by swapping 2 and 1 in b.

• For a = [1, 2, 2] and b = [2, 1, 1], the output should be
  areSimilar(a, b) = false.

  Any swap of any two elements either in a or in b won‘t make aand b equal.

我的解答：

 1 def areSimilar(a, b):
 2     count = 0
 3     if sorted(a) == sorted(b):
 4         for i in zip(a,b):
 5             if i[0] != i[1]:
 6                 count +=1
 7         if count > 2:
 8             return False
 9         else:
10             return True
11     else:
12         return False

膜拜大佬：

def areSimilar(A, B):
    return sorted(A)==sorted(B) and sum([a!=b for a,b in zip(A,B)])<=2
