Question

我尝试将内部字符串数组值与其他数组，堆栈等交换。
示例：

s = [1,2,3,4,5,6,7,8]
output= [1,5,2,6,3,7,4,8]

我的解决方案如下所示，但我认为这不是最佳解决方案。有人可以纠正我的代码效率吗？

[python3]
class Solution:
    def inner_number(self, s):
        i=len(s)//2
        index=1
        while i < len(s):
            for j in range(i,index,-1):
                s[j-1],s[j]=s[j],s[j-1]
            i+=1
            index+=2
        return s

Answer 1



[
    {
    "id": "f98nu4505fd782"
    "firstname": "John",
    "lastname": "Doe",
    "departments": [
        {
            "id": "d8nn83873434",
            "name": "Department 1 Name"
        },
        {
            "id": "9d8n892030e9",
            "name": "Department 2 Name"
        }
        ]
    }
]

Answer 2

s = [1,2,3,4,5,6,7,8,9] 
h = len(s)//2
res= []
if len(s)%2==1:
    res = [j for i in zip(s[:h],s[h:]) for j in i] + [s[-1]]
else:
    res = [j for i in zip(s[:h],s[h:]) for j in i]
print(res)
# output [1, 5, 2, 6, 3, 7, 4, 8, 9]
