输入一个正整数repeat (0
例：括号内是说明
输入：
2 (repeat=2)
10 (money=10分)
13 (money=13分)
输出：
2 (10分有2种换法)
4 (13分有4种换法)
#include "stdio.h"
int main( )
{
int ri, repeat;
int count, fen1, fen2, fen5, money;
scanf("%d", &repeat);
for(ri = 1; ri <= repeat; ri++){
scanf("%d", &money);
count=0;
for(fen5=1;fen5<=19;fen5++)
for(fen2=1;fen2<=48;fen2++)
for(fen1=1;fen1<=money;fen1++)
if(fen5*5+fen2*2+fen1==money)
count++;
printf("%d\n", count);
}
}
