Problem Statement

Given integers a and b with a <= b, print all integers from a up to but not including b, in ascending order, one per line. If a=b, print nothing.

Input

One line contains integers a and b in that order.

Output

One integer in [a,b) per line; no output for an empty interval.

Subtasks

• Subtask 1 (20%): 0 <= a <= b <= 10.
• Subtask 2 (30%): -100 <= a <= b <= 100.
• Subtask 3 (50%): -1000000 <= a <= b <= 1000000.

Examples

Example 1

Input

3 6

Output

3
4
5

Explanation

The integers satisfying 3 <= i < 6 are 3, 4 and 5. The value 6 is excluded.

Example 2

Input

4 4

Output

Explanation

The interval is empty, so the loop executes zero times.
