For loop for array to exchange elements of array?

Answer 1

A hint (I have to go offline for a little while).

This works in Python:

a,b = 1,2 (assigns both at once)

so does this:

myList[i],myList[j] = myList[j],myList[i]

for swapping in place without a temporary variable.

Answer 2

It's not a loop Kirk

Maybe Atef can add some words in question. What do you mean about exchange here?

Answer 3

Wish I could get a list of threads I was following.

It wasn't supposed to provide the answer, since the structure of the array isn't specified. I might have just said "show the array" but I felt a quick boost was more helpful.

The exchange shown should actually make the resulting loop less complex. Trouble with that should have (I hoped) resulted in more detail as you've asked.
