C++ 代码

#include <iostream>

using namespace std;
const int N = 1e5 + 10;
int a[N], b[N];

int main()
{
    int n, m;
    cin >> n >> m;
    for(int i = 0; i < n; i++)scanf("%d", &a[i]);
    for(int i = 0; i < m; i++)scanf("%d", &b[i]);
    int i = 0, j = 0;
    while(i < n && j < m)
    {
        if(a[i] == b[j])i++;
        j++;
    }
    if(i == n)printf("Yes\n");//如果i走到了最后
    else printf("No\n");
    return 0;
}
