如果scanf后面不加上>0就会OLE

#include <iostream>
#include <stdio.h>
using namespace std;

int state[10001] = {0};

int js(int N){
	int n = N;
	if(state[n] > 0) return state[n];
	int cnt = 0;
	while(1){
		if(n%2 == 0) n /= 2;
		else n = 3*n+1;
		cnt++;
		if(n <= 10000 && state[n] > 0) {
			state[N] = cnt+state[n];
			return cnt+state[n];
		}
	}
}

int main() {

	int s, e;
	state[1] = 1;
	while(scanf("%d%d", &s, &e) > 0){
		int start, end;
		if(s == 0 && e == 0) return 0;
		if(s <= e) {
			start = s;
			end = e;
		}
		else{
			start = e;
			end = s;
		}
		int mx = 0;
		for(int i = start; i <= end; i++){
			int ans = js(i);
			if(mx < ans) mx = ans;
		}
		printf("%d %d %d\n", s, e, mx);
	}
	return 0;
}
