Solution
To reverse the first half and second half of the array, follow these steps:
- Read the size of the array (N) and the array elements.
- Split the array into two halves. If the size of the array is odd, the first half will have (N/2) elements and the second half will have (N/2 + 1) elements. If the size is even, both halves will have N/2 elements.
- Reverse the first half of the array. You can do this by swapping the elements at positions i and (N/2 - i - 1), where i ranges from 0 to (N/4 - 1).
- Reverse the second half of the array. You can do this by swapping the elements at positions (N/2 + i) and (N - i - 1), where i ranges from 0 to (N/4 - 1).
- Print the reversed array.
For example, given the input "1 2 3 4 7 8 6 5 4", the array has 9 elements. The first half is "1 2 3 4" and the second half is "7 8 6 5 4". After reversing both halves, the array becomes "4 3 2 1 7 4 5 6 8", which is the expected output.
Please note that the code should be able to handle multiple test cases and pass the hidden test cases as well.
