有大佬帮我看一下吗，前三个测试点没过

#include<iostream>
#include<bits/stdc++.h>
using namespace std;

int main()
{
    int l, m,n=0;
    cin >> l >> m;
    int u, v;
    bool a[10001];
    memset(a, 0, sizeof(a));

    for (int i = 0; i < m; i++)
    {
        cin >> u >> v;
        for (int i = u; i <= v; i++)
            a[i] = 1;
    }
    for (int i = 0; i < l; i++)
    {
        if (a[i] == 1) n++;
    }
    cout << l+1-n << endl;
    return 0;
}

for (int i = u-1; i <= v-1; i++) a[i] = 1;

for(int i=u-1;i<v;i++)

对了那一行是j

#include<iostream>
#include<bits/stdc++.h>
using namespace std;

int main()
{
    int l, m,n=0;
    cin >> l >> m;
    int u, v;
    bool a[10001];
    memset(a, 0, sizeof(a));

    for (int i = 0; i < m; i++)
    {
        cin >> u >> v;
        for (int j = u-1; j <= v-1; j++)
            a[j] = 1;
    }
    for (int i = 0; i < l; i++)
    {
        if (a[i] == 1) n++;
    }
    cout << l+1-n << endl;
    return 0;
}

剩下一个点就是你思路问题了
