283. Move Zeroes
Given an array nums, write a function to move all 0‘s to the end of it while maintaining the relative order of the non-zero elements.
For example, given nums = [0, 1, 0, 3, 12], after calling your function, nums should be [1, 3, 12, 0, 0].
Note:
- You must do this in-place without making a copy of the array.
- Minimize the total number of operations.
public void MoveZeroes(int[] nums) { int zeroCount =0; foreach(var num in nums) { if(num == 0) zeroCount++; } int index=0; for(int i =0;i< nums.Count();i++) { if(nums[i] !=0) nums[index++] = nums[i]; } for(int i = index;i< nums.Count();i++) { nums[i] = 0; } }
public void MoveZeroes(int[] nums) { for (int i = 0, j = 0; i < nums.Count(); i++) { if (nums[i] !=0 ) { if(i!=j) Swap(nums, i,j++); else j++; } } } private void Swap(int[] nums, int i, int j) { int temp = nums[i]; nums[i] = nums[j]; nums[j] = temp; }
