LeetCode in TypeScript
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
/*
Do not return anything, modify nums in-place instead.
*/
function moveZeroes(nums: number[]): void {
let firstZero = 0
for (let i = 0; i < nums.length; i++) {
if (nums[i] !== 0) {
const temp = nums[i]
nums[i] = nums[firstZero]
nums[firstZero] = temp
firstZero++
}
}
}
export { moveZeroes }
