Remove Element

LeetCode題目: 27. Remove Element

My solution:

/**
 * @param {number[]} nums
 * @param {number} val
 * @return {number}
 */
let removeElement = (nums, val) => {
    let k = 0;
    for(let i=0; i<nums.length; i++) {
        if(nums[i] !== val) nums[k++] = nums[i];
    }
    nums.splice(k);
    return k;
};
