Swapping elements in array using c#

Fares Ayyad

Hello

if i have an array consist of 5 integers from 1 to 5 like this

So, i want to swap the last number (5) with the first number (1)

And

Swap the second number (2) with the fourth number (4)

So the number 3 (which is in the middle will stay in the middle with index of 2).

I tried to swap between the first and last number in this manner:

But i don't know if this is true, and what about the second swapping?
