Leetcode Wiggle Sort II problem solution YASH PAL, 31 July 2024 In this Leetcode Wiggle Sort II problem solution You are given an integer array nums, reorder it such that nums[0] < nums[1] > nums[2] < nums[3]…. You may assume the input array always has a valid answer. Topics we are covering Toggle Problem solution in Python.Problem solution in Java.Problem solution in C++. Problem solution in Python. class Solution: def wiggleSort(self, nums: List[int]) -> None: nums.sort() for i in range(len(nums)//2): nums.insert(len(nums)//2 - i - 1,nums.pop()) if len(nums) % 2 != 0: nums.insert(0,nums.pop()) nums.reverse() if len(nums)>1 and nums[-1] == nums[-2]: for i in range(len(nums)): if nums[i] < nums[-2] and nums[-1] < nums[i+1]: nums[i],nums[-1] = nums[-1],nums[i] break Problem solution in Java. class Solution { public void wiggleSort(int[] nums) { int[] tempArr=Arrays.copyOf(nums,nums.length); Arrays.sort(tempArr); int t=tempArr.length-1; for(int i=0;i<nums.length;i++){ if(i%2!=0){ nums[i]=tempArr[t]; tempArr[t]=-1; --t; } } t=0; int k=0; for(int i=nums.length-1;i>=0;i--){ if(i%2==0){ nums[i]=tempArr[t]; t++; } } } } Problem solution in C++. class Solution { public: void wiggleSort(vector<int>& nums) { vector<int> sorted(nums); sort(sorted.begin(),sorted.end()); int idx = sorted.size()-1; for(int i=1; i<nums.size(); i+=2) nums[i] = sorted[idx--]; for(int i=0; i<nums.size(); i+=2) nums[i] = sorted[idx--]; return; } }; coding problems solutions
