题目:
Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array.
Note:
You may assume that nums1 has enough space (size that is greater or equal to m + n) to hold additional elements from nums2. The number of elements initialized in nums1 and nums2 are m and n respectively.
class Solution(object):
def merge(self, nums1, m, nums2, n):
"""
:type nums1: List[int]
:type m: int
:type nums2: List[int]
:type n: int
:rtype: void Do not return anything, modify nums1 in-place instead.
"""
i,j = m-1,n-1
while i>=0 and j>=0 :
if nums1[i] > nums2[j]:
nums1[i+j+1] = nums1[i]
i -= 1
else:
nums1[i+j+1] = nums2[j]
j -= 1
if j>=0:
nums1[:j+1] =nums2[:j+1]
# return nums1 之前我写返回值,提交显示错误
a = Solution()
print a.merge([],0,[1],1)
