这段代码莫名其妙出错了，有没有大佬帮忙看一下

#include <bits/stdc++.h>
using namespace std;
int n,m,w,f[100001]={0},c[100001],d[100001],a,b,ans[100001][100001];
int father(int num){
    if(f[num]==num)
        return num;
    f[num]=father(f[num]);
    return f[num];
}
int main(){
    cin>>n>>m>>w;
    for(int i=1;i<=n;i++)
        f[i]=i;
    for(int i=1;i<=n;i++)
        cin>>c[i]>>d[i];
    for(int i=1;i<=m;i++){
        cin>>a>>b;
        f[father(b)]=father(a);
    }
    for(int i=1;i<=n;i++)
        if(f[i]!=i){
            c[father(i)]+=c[i];
            d[father(i)]+=d[i];
            c[i]=0;
            d[i]=0;
        }
    for(int i=1;i<=n;i++)
        for(int j=1;j<=w;j++)
            if(j>=c[i])
                ans[i][j]=max(ans[i-1][j],ans[i-1][j-c[i]]+d[i]);
            else
                ans[i][j]=ans[i-1][j];
    cout<<ans[n][w];
    return 0;
}

报错如下：
