Remove Duplicates from Sorted Array II

/*2017.10.7//LeedCode : Remove Duplicates from Sorted Array II 需要一个计数器,如果重复次数小于2，就把这个元素放到新数组里.*/int removeDuplicates(int* nums, int numsSize) {        int k = 0, i, cnt = 1;;    if(numsSize == 0)        return numsSize;        for(i = 1; i < numsSize; i++){        if(nums[k] == nums[i]){            cnt++;            if(cnt == 2)                nums[++k] = nums[i];                    }else{            cnt = 1;            nums[++k] = nums[i];        }    }        return k+1;}
