输入三个整数，x,y,z，最终以从小到大的方式输出

<!--<script>

var x=prompt("请输入数字")

var y=prompt("请输入数字")

var z=prompt("请输入数字")

//if(x<y&&x<z&&y<z){

alert (x+","+y+","+z)

}

if(x<z&&x<y&&z<y){

alert (x+","+z+","+y)

}

if(y<z&&y<x&&z<x){

alert (y+","+z+","+x)

}

if(y<x&&y<x&&x<z){

alert (y+","+x+","+z)

}

if(z<y&&z<x&&y<x){

alert (z+","+y+","+x)

}

if(z<x&&z<y&&x<y){

alert (z+","+x+","+y)

}
