改变一下学习策略,多看discuss,看博客总是乱七八糟。
- Move Zeroes
For example, given nums = [0, 1, 0, 3, 12], after calling your function, nums should be [1, 3, 12, 0, 0].
Note:
You must do this in-place without making a copy of the array.
Minimize the total number of operations.
class Solution(object):
def moveZeroes(self, nums):
"""
:type nums: List[int]
:rtype: void Do not return anything, modify nums in-place instead.
"""
for num in nums:
if num == 0:
nums.remove(num)
nums.append(num)
- Majority Element
思路:找出现次数超过数组长度一半的元素
class Solution(object):
def majorityElement(self, nums):
"""
:type nums: List[int]
:rtype: int
"""
return sorted(nums)[len(nums)//2]
