Generate Integer Sequence

Background

Congcong is currently learning how to generate number sequences. He would like your help to write a program that can generate a specific integer sequence based on given start and end numbers.

Problem Description

Given start and end numbers, return a new array containing the sequence of integers from start up to but not including end. For example, if start=5 and end=10, the result is {5, 6, 7, 8, 9}. The end number end will be greater than or equal to the start number start. Note that a length-$0$ array is valid.

Input Format

Input is given from standard input in the following format.

start end

Output Format

Output should be printed to standard output in the following format.

[num1, num2, ..., numK]

Sample

5 10

[5, 6, 7, 8, 9]

11 18

[11, 12, 13, 14, 15, 16, 17]

1 3

[1, 2]

Sample Explanation

For the first sample, start is $5$ and end is $10$. We need to generate an integer sequence starting from $5$ and ending before $10$ (not including $10$), which is $5, 6, 7, 8, 9$. Thus, the output is [5, 6, 7, 8, 9].
