leetcode--题1

#include <iostream>
#include <vector>
#include <algorithm>

using namespace std;

int main()
{
    int a[] = { 1,2,3,4,5,5,6,7,7,8,8,8,9,9,9,10,10 };
    vector<int>res(a, a + 17);
    res.erase(unique(res.begin(), res.end()),res.end());
    for (auto i : res)
        cout << i << ' ';
    system("pause");
    return 0;
}

解法二：

#include <iostream>
#include <vector>
#include <algorithm>

using namespace std;

int main()
{
    int a[] = { 1,2,3,4,5,5,6,7,7,8,8,8,9,9,9,10,10 };
    cout << a[0] << " ";
    for (int i = 1; i < 17; ++i)
    {
        if (a[i] == a[i - 1])continue;
        else cout << a[i] << ' ';
    }
    system("pause");
    return 0;
}
