java代码找零钱代码 java代码在哪里找( 二 )

Scanner sc=new Scanner(System.in);
float money=(float)sc.nextDouble();//用float吧double计算有时会出问题
for(wy=1;wy=0;wy--)
{
for(ly=2;ly=0;ly--)

找零钱问题 [贪心算法](java实现）public getMin{
public int MinNumber=0;
public int findMax(int[] a){
for(int i=0;ia.length;i++){
if(a[i]==0) return a[--i];
}
return a[a.length-1];
}
public boolean Compare(int a,int b){
public boolean flag=true;
if(ab)flag=flase;
return flag;
}
public int getMinNumber(int[] M,int Money){
int[] findM=new int[M.length];
int index=0;
for(int i=0;iM.length;i++){
boolean f = this.Compare(M[i],money)
if(f)findM[index++]=M[i];
}
int max = this.findMax(findM);
MinNumber++;
if((Money-max)!=0) {
getMinNumber(M,Money-max)
}
return MinNumber;
}
public int[] Start(){
System.out.println("请输入查询组数");
int group=System.in.read();
int[] M={1,2,5,10,20,50,100};
int[] Result = new Int[group];
int index=0;
while (group--0){
System.out.println("请输入金额");
int money=System.in.read();
Result[index++] = getMinNumber(M,money);
MinNumber=0;
}
}
public void print(int[] MinNumber){
for(int i=0;iMinNumber.length.i++){
System.out.println(MinNumber[i]+" ");
}
}
}
public static void main(String[] args){
new getMin().print(new getMin().Start());
}
没测试啊，有问题请勿喷，呵呵
