求助

这个代码连exe文件都编译不了，请问有没有路过的大佬顺手调一下？

#include <bits/stdc++.h>
using namespace std;
const int MAXLEN = 100000;
int c[MAXLEN+1][MAXLEN+1];
int x[100005],y[100005];
int main(){
    //freopen(“lcs.in”, “r”, stdin);
    //freopen(“lcs.out”, “w”, stdout);
    int n;
    cin >> n;
    for(int i = 0;i < n;i++){
        cin >> x[i];
    }
    for(int i = 0;i < n;i++){
        cin >> y[i];
    }
    memset(c, 0, sizeof(c));
    for(int i = 1;i <= n;i++){
        for(int j = 1;j <= n;j++){
            if (x[i] == y[j]){
                c[i][j] = c[i-1][j-1] + 1;
            }
            else{
                if (c[i-1][j] > c[i][j-1]){
                    c[i][j] = c[i-1][j];
                }
                else{
                    c[i][j] = c[i][j-1];
                }
            }
        }
    }
    cout << c[n-1][n-1] << endl;
    return 0;
}
