CSP 202212-2 训练计划

想问下下面这个代码为什么只有70分？

#include<iostream>
#include<cstring>
using namespace std;

int main() {
    int m,n;
    cin>>m>>n;
    int a[n],b[n];
    for(int i=0; i<n; i++) {
        cin>>a[i];
    }
    for(int i=0; i<n; i++) {
        cin>>b[i];
    }
    //更新最早开始时间和结束时间
    for(int i=0; i<n; i++) {
        if(a[i]==0) {
            cout<<"1"<<" ";
            a[i]=1;
            b[i]+=a[i];
        } else {
            a[i]=b[a[i]-1];
            b[i]+=a[i];
            cout<<a[i]<<" ";
        }
    }
    //判断是否超时
    bool flag=1;
    for(int i=0; i<n; i++) {
        if(b[i]-1>m) flag=0;//超时flag为0
    }
    cout<<endl;
    if(flag==1) {
        for(int i=0; i<n; i++) {
            cout<<m-b[i]+2<<" ";
        }
    }
    return 0;
}
