var
one=two=five0;//one代表一块的张数,two代表两块的张数
five代表五块
//
的张数
且
one+two+five=10(共十张钞票)
for(
one=0;one0<=10;one++)
//一块的从
0张
到10张依次组合
{
for(two=0,two<=(10-one);two++)//在一块从0张到10的组合中,在依次组合2元面额的数量
//二元面额的张数最少有
0张,最大有
10-one张
{
five=10-one-two;
//在确定了一块和两块的的张数后,10张钞票中
剩下的就是五
//的了
if(one1+two2+five5==18)
如果他们三中面额的钞票组合起来是18块
那就是我们要的组合
{
这里是输出结果的语句,这个代码就不用我写了哈
}
}
}
到此,程序结束``运行就用结果(先给你看看我的运行结果
如下:)
一块:2张####两块:8张####五块:0张
一块:5张####两块:4张####五块:1张
一块:8张####两块:0张####五块:2张
var m = 100000;
var i = 0;
while(m > 5000){
if(m > 50000){
m -= 005 m;
}else{
m -= 5000;
}
i++;
}
consolelog(i);
(function(){
function test(x){
let y;
for(y=0;y<=255;y++){
if(parseInt(x+""+y)%97==1){
break;
}
}
return y
}
function random(min, max){
let n = max - min + 1
return Mathceil((Mathrandom() n)) - 1 + min
}
let x = random(0, 999999)
return parseInt(String(x) + String(test(x))) % 97 === 1 && 0 <= test(x) && test(x) <= 255
})()
x是一个随机数,要求x 和 test(x) 拼接(不是相加)起来的数字处以97刚好余1,并且test(x)大于等于0小于等于255
while(true){
var obj = prompt("输入一个整数:","");
if(/^\+\d+$/test(obj)){
var sum = 0;
for(var i = 1; i <= obj; i++){
var x = 1;
for(var j = 1; j <= i; j++){
x = j;
}
sum += x;
}
alert("1的阶乘到"+obj+"的阶乘的和: " + sum);
break;
}else{
continue;
}
}
