PROGRAMMING CHALLENGE

This one should be difficult enough for you guys,

Write a function foo that takes a number n and returns a function that takes a number i, and returns n incremented by i.


My submission, in Scheme


(define (foo num)
  (lambda (x) (+ x num)))

>Write a function foo that takes a number n and returns a function that takes a number i, and returns n incremented by i.
a=parseInt(prompt("Enter a number",0));;
eval("function newf(i){return a+i}")
newf(10);
