C++解答

#include<cstdio>
#include<string>
using namespace std;

char s[101];

int main()
{
	string a,b,c;
	int i,t;
	while(scanf("%s",s)!=EOF)
	{
		a=s;
		if(a==".")
			break;
		b="";
		for(i=0;;i++)
		{
			b+=a[i];
			if(a.size()%b.size())
				continue;
			c="";
			t=0;
			while(c.size()<a.size())
			{
				c+=b;
				t++;
			}
			if(c==a)
			{
				printf("%d\n",t);

Java解答

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		while (true) {
			String input = sc.nextLine();
			if (input.equals(".")) {
				break;
			}
			System.out.println(foo(input));
		}
		sc.close();
	}

	private static int foo(String input) {
		for (int i = 1; i <= input.length(); i++) {
			if (input.length() % i == 0) {
				String unit = input.substring(0, i);
				boolean find = true;
				for (int j = 0; j < input.length(); j += i) {
					String temp = input.substring(j, j + unit.length());
					if (!temp.equals(unit)) {
						find = false;
						break;
					}
				}
				if (find) {
					return input.length() / unit.length();
				}
			}
		}
		return 1;
