Problem Description
There are at least P% and at most Q% students of HDU are ACMers, now I want to know how many students HDU have at least?
Input
The input contains multiple test cases.
The first line has one integer,represent the number of test cases.
The following N lines each line contains two numbers P and Q(P < Q),which accurate up to 2 decimal places.
The first line has one integer,represent the number of test cases.
The following N lines each line contains two numbers P and Q(P < Q),which accurate up to 2 decimal places.
Output
For each test case, output the minumal number of students in HDU.
Sample Input
113.00 14.10
Sample Output
15
题意:acmer的人数在P%和Q%之间,最少P%,最多Q%,要求最少有多少个acmer,因为一个数据是最多
一个是最少,所以两个数据的人数不能相同,而且P%一定少于Q%
#include<stdio.h>#include<iostream>#include<string.h>#include<algorithm>using namespace std;int main(){ int n,sum; double a,b; cin>>n; while(n--){ cin>>a>>b; sum=1;//总数 while(1){ if((int)(a*sum/100)<(int)(b*sum/100)){ break; } sum++; } cout<<sum<<endl; }}
