求 nums[0] + nums[ n ] === target 的 用 Map var twoSum = function(nums, target) { let map = new Map() for(let i =0;i < nums.length; i++){ let x = target-nums[i] if(map.has(x)){ return [map.get(x),i] } map.se.

var findMedianSortedArrays = function(nums1, nums2) { let num1 = null let list = [...nums1 , ...nums2] let otherlist = list.sort( (a,b) => a -b ) // 升序 let middlenum = Math.floor(otherlist.length / 2) // 取中间数 if(otherlist.length % 2
