What is a code to reverse all elements of given circular array starting from index K and the other steps required given the following:
Reverse all elements of given circular array starting from index K | Function to print array arr [ ].
Print the array.
Function to reverse elements of given circular array starting from index k.
Initialize two variables as start = k and end = k - 1.
Initialize count = N / 2.
Loop while count > 0.
Swap the elements at index ( start % N ) and ( end % N ).
Update the start and end.
If end equals to - 1 set end = N - 1.
Print the circular array.
Driver Code.
Function Call"
How can the above be solved in Python?
