7，8，9，10都wa，因为实在不会处理重复的数据，求大佬帮我看看怎么改。

#include <cstdio>
#include <queue>
#define ll long long
using namespace std;

priority_queue<ll, vector<ll>, greater<ll>> q;

int main() {
    int n;
    scanf("%d", &n);
    for (int i = 0; i < n; i++) {
        ll temp;
        scanf("%lld", &temp);
        q.push(temp);
    }

    int min = 1000000;
    int lenth = 1;
    ll last = q.top();
    q.pop();
    int flag = 0;
    for (int i = 1; i < n; i++) {
        ll temp2 = q.top();

        q.pop();
        if (temp2 == last + 1) {
            lenth++;
        } else if (temp2 == last) {
            flag = 1;
        } else {
            if (min > lenth) {
                min = lenth;
            }
            lenth = 1;
        }
        last = temp2;
    }

    if (min > lenth) {
        min = lenth;
    }
    printf("%d", min);
    return 0;
}
