I need expected of the test case of the problem ROTATION. I know it’s an ongoing competion but I am just asking for a explanation of the test cases. Thank you.

Input:
N=5 M=5
- A[1]=5 A[2]=4 A[3]=3 A[4]=3 A[5]=9
- R 1 —> output the value of the first element of the array that is A[1]=5 so out put is 5
- C 4 —> rotate the given array 4 times in clock wise direction that is:
- initial —> 5 4 3 3 9
- after 1st rotation —> 4 3 3 9 5 (first 5 to last position)
- after 2nd rotation —> 3 3 9 5 4 (first 4 to last position)
- after 3rd rotation —> 3 9 5 4 3 (first 3 to last position)
- after 4th rotation —> 9 5 4 3 3 (first 3 to last position)
- R 5 —> output the value of the fifth element of the array that is A[5]=5 so out put is 3
- A 3 —> rotate the given array 3 times in anti clock wise direction that is:
- now present array is 9 5 4 3 3
- after 1st rotation —> 3 9 5 4 3 (last 3 to first position)
- after 2nd rotation —> 3 3 9 5 4 (last 3 to first position)
- after 3rd rotation —> 4 3 3 9 5 (last 4 to first position)
- R 2 —> output the value of the second element of the array that is A[2]=3 so out put is 3
Hope this will be helpful to you
