How can I display the equation?

Question

https://code.sololearn.com/We1rSdjApTeH/#html

I want this to display the equation it used to get the final result

So for the challenge example, they used 135

So the equation is 1^1+3^2+5^3

How can I make it display this?

Remember, I don't want that specific equation
I want it to show the equation for the number the user typed

So if the input is..lets say 3783

it'd be 3^1+7^2+8^3+3^4

Answer 1

Try

var output = input.toString().split("").map((v,i)=>v+"^"+(i+1)).join("+");
