直接上代码 `func isValid(_ s: String) -> Bool {         if s.count%2 == 1 {             return false    

上代码 func maxArea(_ height: [Int]) -> Int {     var start = 0     var end = height.count-1     var ar

上代码 ``func findMedianSortedArrays(_ nums1: [Int], _ nums2: [Int]) -> Double {     let totalLength =

`func lengthOfLongestSubstring(_ s: String) -> Int {     var maxCount = 0     var currentString = ""

直接上代码 没打败几个人 `public class ListNode {       public var val: Int       public var next: ListNode?
