Interlace odd / even from A to B.

     Interlace odd / even from A to B.

                                          

Two numbers A and B are passed as input.
A number N is also passed as the input.
The program must print the odd numbers from A to B (inclusive of A and B) interlaced with the even numbers from B to A.

Input Format:

The first line denotes the value of A.
The second line denotes the value of B.

Output Format:
The odd and even numbers interlaced, each separated by a space.

Boundary Conditions:
1 <= A <= 9999999
A <  B <= 9999999

Example Input/Output 1:

Input:
5
11

Output:
5 10 7 8 9 6 11

Explanation:
The odd numbers from 5 to 11 are 5 7 9 11
The even numbers from 11 to 5 (that is in reverse direction) are 10 8 6
So these numbers are interlaced to produce 5 10 7 8 9 6 11

Example Input/Output 2:
Input:
414

Output:
14 5 12 7 10 9 8 11 6 13 4

Explanation:

The odd numbers from 4 to 14 are 5 7 9 11 13
The even numbers from 14 to 4 (that is in reverse direction) are 14 12 10 8 6 4

So these numbers are interlaced to produce 14 5 12 7 10 9 8 11 6 13 4(Here as the even numbers count are more than the odd numbers count we start with the even number in the output)

Example Input/Output 3:

Input:
3
12
Output:
3 12 5 10 7 8 9 6 11 4

Explanation:

The odd numbers from 3 to 12 are 3 5 7 9 11
The even numbers from 12 to 3 (that is in reverse direction) are 12 10 8 6 4
So these numbers are interlaced to produce 3 12 5 10 7 8 9 6 11 4

Code:

1. import java.util.*;
2. class Hello {
3. 
   
4.     public static void main(String[] args) {
5.    Scanner sc=new Scanner(System.in);
6.    int a=sc.nextInt();
7.    int b=sc.nextInt();
8.    int i,j;
9.    for(i=a,j=b;i<=b;i++,j--)
10.             {
11.                 if(i%2==1)
12.                     System.out.print(i+" ");
13.                 if(j%2==0)
14.                     System.out.print(j+" ");
15.             }
16. }
17. }
