『壹』 一演算法題java實現，有一分錢，兩分錢，五分錢，加起來等於10元錢。有多少種方法，並列印出來高手指教
一共50401組數據
public class ABC {
public static void main(String args[]) {
final int total = 1000;/穗渣/一共1000分
int count = 0;
for(int one = 0; one <= total / 1; one++){//察好1分錢數目
for(int two = 0; two <= total / 2; two++){//2分錢數目
for(int five = 0; five <= total / 5; five++){//5分錢數目
if(one*1 + two*2 + five *5 == total){
System.out.println("1*" + one + "敗族鉛 + 2*" + two + " + 5*" + five + "= 1000" );
count++;
}
}
}
}
System.out.println("Total possible " + count + " group!");
}
}
------------------
。。。。。
1*996 + 2*2 + 5*0= 1000
1*998 + 2*1 + 5*0= 1000
1*1000 + 2*0 + 5*0= 1000
Total possible 50401 group!
『貳』 Java定義一個表示人民幣的類Money，
public class Money {
private int yuan;
private int jiao;
private int fen;
public Money(int yuan,int jiao, int fen){
this.yuan=yuan;
this.jiao=jiao;
this.fen=fen;
}
public void show(){
System.out.printf("%d元回%d角%d分",yuan,jiao,fen);
}
public static void main(String[] args) {
答Money m=new Money(4,5,6);
m.show();
}
}
『叄』 JAVA程序 輸入一串數字如12341289.23，輸出萬千百十元角分。高手幫忙！謝謝
//將人民幣金額轉換為大寫
function upDigit(n){
var fraction = ["角","分"];
var digit = ["零","壹","貳","叄","肆","伍","陸","柒","捌","玖"];
var unit = [["元","萬","億"],["","拾","佰","仟"]];
var head = n<0?"負":"";
n = Math.abs(n);
var s = "";
for(var i=0; i<fraction.length; i++){
s += (digit[Math.floor(n*10*Math.pow(10,i))%10]+fraction[i]).replace(/零./,"");
}
s = s||"整";
n = Math.floor(n);
for(var i=0; i<unit[0].length && n>0; i++){
var p = "";
for(var j=0; j<unit[1].length && n>0; j++){
p = digit[n%10] + unit[1][j]+p;
n = Math.floor(n/10);
}
s = p.replace(/(零.)*零$/,"").replace(/^$/,"零") + unit[0][i] + s;
}
return head + s.replace(/(零.)*零元/,"元").replace(/(零.)+/g,"零").replace(/(^整$)/,"零元整");
}
