• 문제를 제대로 이해하지 못함.
• O(n) 개념 부족.

Do not allocate extra space for another array. You must do this by modifying the input array in-place with O(1) extra memory.

var removeDuplicates = function(nums) {
    // return [...new Set(nums)];
        for (let i = 0; i < nums.length; i++) {
        if (nums[i] === nums[i + 1]) {
            nums.splice(i, 1);
            i--;
        }
    }
};
