天天码code，预防老年痴呆！把25人推广成N，把7推广成M，下面是个JAVA code：
public void func(int n, int m) {
ArrayList<String> people = new ArrayList<String>();
for (int i = 1; i <= n; i++)
{
people.add(new String(String.valueOf(i)));
}
int ct = 1;
int index = 0;
while(people.size() > 1)
{
if (ct%m==0)
{
index = index%people.size();
people.remove(index);
index --;
}
ct++;
index++;
}
System.out.println("Last Person: " + people.get(0).toString());
}
