Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array.
Note:
- The number of elements initialized in nums1 and nums2 are m and nrespectively.
- You may assume that nums1 has enough space (size that is greater or equal to m + n) to hold additional elements from nums2.
Example:
Input: nums1 = [1,2,3,0,0,0], m = 3
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: None Do not return anything, modify nums1 in-place instead.
"""
i=m-1
j=n-1
end=i+n
while(i>=0 and j>=0):
if(nums2[j]>=nums1[i]):
nums1[end]=nums2[j]
j-=1
end-=1
else:
nums1[end]=nums1[i]
i-=1
end-=1
if(i==-1):
while(j>=0):
nums1[end]=nums2[j]
j-=1
end-=1
nums2 = [2,5,6], n = 3 Output: [1,2,2,3,5,6]
题意:给两个有序list,把nums2并到nums1中,nums1足够大
解法:从最后一个开始比较
