LeetCode 88. 合并两个有序数组

示例:

输入:
nums1 = [1,2,3,0,0,0], m = 3
nums2 = [2,5,6],       n = 3

输出: [1,2,2,3,5,6]

class Solution:
    def merge(self, nums1: [int], m: int, nums2: [int], n: int) -> None:
        """
        Do not return anything, modify nums1 in-place instead.
        """
        for i in range(len(nums1)-m):
            nums1.pop()
        for j in range(n):
            nums1.append(nums2[j])
        nums1.sort()
