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;
}
