26. 删除有序数组中的重复项

class Solution {
public:
    int removeDuplicates(vector<int>& nums) {
        int head = 0, curIndex = 0, target = INT_MIN;
        for(; curIndex < nums.size(); ++curIndex){
            if(nums[curIndex] != target){
                nums[head++] = nums[curIndex];
                target = nums[curIndex];
            }
        }
        return head;
    }
};
