reverse array code did not work

[subhanssingh]

In for loop of reversing array there should be i-- not i++.

that's right

Try this..

That's right, Here's what the code does:

The code declares a new integer array 'a' with some initial values {1, 2, 3, 4, 5, 6, 7, 8}.

It declares a new integer array 'b' with the same length as array 'a'.

It uses 'a' for loop to iterate through array 'a' from the end to the beginning. During each iteration, it assigns the current value of 'a[i]' to the corresponding position in array 'b', starting from the beginning.

Finally, it uses a for-each loop to print out each element in array 'b' in the reversed order.

So the output of the program would be:' 8 7 6 5 4 3 2 1'.

it is also possible to reverse the same array using constant space with O(n) time complexity .//

class Main {
    public static void main(String[] args) {
        int[] array = {1,2,3,4,5};
        
        **// it just return the array in reverse manner without any extra space or any temp array //**
        for (int i = array.length-1; i>=0; i--) {
            System.out.print(array[i] +" ");
        }
    }
}
