C++ program (严格按照题目来)
Posted by lz1 12 Jan 2012 17:49
// 严格按照题目来
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <algorithm>
using namespace std;

const int p = 10000;
double xs, ys;
int x, y, ans;

int main(void)
{
scanf ("%lf%lf", &xs, &ys);
ans = 1, x = y = 0;
// 严格按照题目来 (more than ... ; less than ... )
ys -= 1E-10, xs += 1E-10;
while (x == y)
ans++, x = int (ans * xs) / 100, y = int (ans * (ys)) / 100;
printf ("%d", ans);
return 0;
}

because it said "more than P%" and "less than Q%", so it can't be equal, you have to shorten interval, just add or sub 1E-10
（因为题目是说“more than P%” 和 “less than Q%”，因此不能相等，所以两边的区间都要往里面再缩小一点，只要加或减1E-10就行）
