This helped me out thanks
how it worked please can u explain me??
You can determine where in the array each element will end up with a simple calculation using the number of elements (n), the number of times you perform the operation (k), and an incrementing variable (use a for loop). Try to figure out the equation and use that answer as the array assignment. You need to use the while loop right before the array assignment because sometimes the calculation you perform will leave you with an array assignment value that is greater (hint) than the amount of array values so you just repeat the same equation until you get a valid value (something < n).
Here i have explained it in detail.
