# 4. Median of Two Sorted Arrays

Given two sorted arrays nums1 and nums2 of size m and n respectively, return the median of the two sorted arrays.

Example 1:

``````Input: nums1 = [1,3], nums2 = [2]
Output: 2.00000
Explanation: merged array = [1,2,3] and median is 2.
``````

Example 2:

``````Input: nums1 = [1,2], nums2 = [3,4]
Output: 2.50000
Explanation: merged array = [1,2,3,4] and median is (2 + 3) / 2 = 2.5.
``````

Example 3:

``````Input: nums1 = [0,0], nums2 = [0,0]
Output: 0.00000
``````

Example 4:

``````Input: nums1 = [], nums2 = [1]
Output: 1.00000
``````

Example 5:

``````Input: nums1 = [2], nums2 = []
Output: 2.00000
``````

## Solution

``````/**
* @param {number[]} nums1
* @param {number[]} nums2
* @return {number}
*/
var findMedianSortedArrays = function(nums1, nums2) {
let sortedArray = [...nums1, ...nums2].sort((a,b) => a-b);
let median = 0;

if (sortedArray.length % 2 !== 0) {
median = sortedArray[Math.floor(sortedArray.length / 2)];
} else {
median = (sortedArray[(sortedArray.length/2)] + sortedArray[(sortedArray.length/2) -1])/2;
}

return median;
};
