283. Move Zeroes
Easy
Given an integer array nums, move all 0’s to the end of it while maintaining the relative order of the non-zero elements.
Note that you must do this in-place without making a copy of the array.
Example 1:
Input: nums = [0,1,0,3,12]
Output: [1,3,12,0,0]
Example 2:
Input: nums = [0]
Output: [0]
Constraints:
1 <= nums.length <= 104-231 <= nums[i] <= 231 - 1
Follow up: Could you minimize the total number of operations done?
Solution
func moveZeroes(nums []int) {
var j int
for i := 0; i < len(nums); i++ {
if nums[i] != 0 {
nums[j], nums[i] = nums[i], nums[j]
j++
}
}
}
