LeetCode: Remove Duplicates from Sorted Array II
题目
https://oj.leetcode.com/problems/remove-duplicates-from-sorted-array-ii/
分析
和Remove Duplicates from Sorted Array类似,
从前向后遍历该序列, 如果该元素和前一元素相同则重复数加1。
只不过只有重复数小于等于2时才把该元素排到数组前面。
代码
class Solution
{
public:
int removeDuplicates(int A[], int n)
{
if (n < 1)
return n;
int count = 1;
int dup_times = 1;
for (int i = 1; i < n; i++)
{
if (A[i] == A[i-1])
dup_times++;
else
dup_times = 1;
if (dup_times <= 2)
A[count++] = A[i];
}
return count;
}
};
