LeetCode 88 - Merge Sorted Array Problem

Problem Statement

Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array.


  • The number of elements initialized in nums1 and nums2 are m and n respectively.
  • You may assume that nums1 has enough space (size that is greater or equal to m + n) to hold additional elements from nums2.


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

Output: [1,2,2,3,5,6]


class Solution: def merge(self, nums1: List[int], m: int, nums2: List[int], n: int) -> None: m-=1 n-=1 counter=len(nums1)-1 while m>=0 and n>=0: if nums1[m]=0: nums1[counter] = nums2[n] counter-=1 n-=1 return nums1
