Question

如何编写一个返回前一个函数的相反参数的函数？该函数可以返回int，char，string等。示例： f = pow（2,3）= 8（原始） g = pow（3,2）= 9（反向参数）

capitalize_first_and_join第一，第二，第三= FIRSTsecond，第三（原始） capitalize_first_and_join第一第二第三= THIRDsecondfirst（反向参数）

最好与编码器连接，您=编码器，最好，那个，您（原始） join_with最好的编码器是您=您，最好的编码器（反向参数）

我需要创建的函数名称为reversed_args（f）

此致

var can;
var ctx;

function init(){
  can=document.getElementById("Canvas");
  ctx=can.getContext("2d");
  ctx.canvas.width  = window.innerWidth;
  ctx.canvas.height = window.innerHeight;
  DrawSlope(1,20);
}

function DrawSlope(x,y)
{
   var firstPoint = [x,0];
   var secondPoint = [1,x+y];

WritePointToHTML(firstPoint[0],firstPoint[1],secondPoint[0],secondPoint[1]);
}

function WritePointToHTML(x,y,xTwo,yTwo)
{
ctx.beginPath();
ctx.moveTo(x, y);
ctx.lineTo(xTwo, yTwo);
ctx.stroke();
}
