There are two sorted arrays nums1 and nums2 of size m and n respectively.

Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)).

Example 1:

nums1 = [1, 3]
nums2 = [2] The median is 2.0

Example 2:

nums1 = [1, 2]
nums2 = [3, 4] The median is (2 + 3)/2 = 2.5 给两个已排序的数组,求中位数。
//我的解法比较常规,循环,把小的数添加到新数组,直到两个输入数组为空
/**
* @param {number[]} nums1
* @param {number[]} nums2
* @return {number}
*/
var findMedianSortedArrays = function(nums1, nums2) {
var arr=[];
if(nums2.length===0&&nums1.length0==0)return 0;
while(nums2.length!==0||nums1.length!==0){
if(nums1.length === 0){//数组1为空,把目标数组和数组2拼接返回给目标数组
arr = [].concat(arr,nums2);
nums2.length = 0;
}else if (nums2.length === 0) {
arr = [].concat(arr,nums1);
nums1.length = 0;
}else{//判断大小,小的删除元素并添加到目标中
arr[arr.length] = nums2[0] > nums1[0] ? nums1.shift() : nums2.shift();
}
}
return !(arr.length%2)?(arr[arr.length/2]+arr[arr.length/2-1])/2:arr[Math.floor(arr.length/2)];//返回目标数组的中位数
};

这题热门解法写的很多,而且不熟悉其语法,时间关系没有研究。留待以后吧
