# Data Structures & Algorithms using Rust: Merge Sorted Array Sivakumar
Learning rust
Updated on ・1 min read

As part of Data Structures and Algorithms implementation using Rust, today we will explore `Merge Sorted Array` problem.

Leetcode problem link: https://leetcode.com/problems/merge-sorted-array/

###### Problem Statement
``````Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array.
``````
###### Instructions
``````Note:

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 equal to m + n) to hold additional elements from nums2.
Example:

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

Output: [1,2,2,3,5,6]

Constraints:

-10^9 <= nums1[i], nums2[i] <= 10^9
nums1.length == m + n
nums2.length == n
``````
###### Solution

Find below the implementation using Rust

``````impl Solution {
pub fn merge(nums1: &mut Vec<i32>, m: i32, nums2: &mut Vec<i32>, n: i32) {
let mut m_i: usize = m as usize;
for i in 0..n {
nums1[m_i] = nums2[i as usize];
m_i += 1;
}
nums1.sort_unstable()
}
}
``````
