In Python 3, you need to change lines 3, 7, and 11.

1. line 3 - our indexing starts at 0 so you need to change the formula to accommodate such condition
2. line 7 - ed should start at the 2nd to the last element, not the last element because you already swapped the last element to the mid element
3. line 11 - ed should decrease so that the loop condition will end

i tried in python c# java 8 output is correct still it is showing wrong answer

does anyone have idea why?

Python 3 didn't work but Java 8 worked.

Does anyone know if this answer supports Ruby? I keep getting the error:

Traceback (most recent call last): File "Solution.py", line 174, in run_custom_checker(t_obj, r_obj) File "Solution.py", line 75, in run_custom_checker system_code = code_data[t_obj.submission_language].strip() KeyError: u'ruby'

Java 8: public static void findZigZagSequence(int [] a, int n){ Arrays.sort(a); int mid = (n - 1)/2;// first modified int temp = a[mid]; a[mid] = a[n - 1]; a[n - 1] = temp;

    int st = mid + 1;
    int ed = n - 2;//second modified
    while(st <= ed){
        temp = a[st];
        a[st] = a[ed];
        a[ed] = temp;
        st = st + 1;
        ed = ed - 1;// modified
    }
    for(int i = 0; i < n; i++){
        if(i > 0) System.out.print(" ");
        System.out.print(a[i]);
    }
    System.out.println();
}

}
