Problem Statement

Print all the integers that satisfies the following in ascending order:

Among the integers between A and B (inclusive), it is either within the K smallest integers or within the K largest integers.

Constraints

1 \leq A \leq B \leq 10^9

1 \leq K \leq 100

All values in input are integers.

Input

Input is given from Standard Input in the following format:

A B K

Output

Print all the integers that satisfies the condition above in ascending order.

Solution in Python (3.4.3) (judge verdict: Accepted)

# -*- coding: utf-8 -*-

# 3つの数字をリストから数値の変数に
input_list = input().split()
start_num = int(input_list[0])
end_num = int(input_list[1])
range_num = int(input_list[2])

result_list = []
for i in range(start_num, end_num + 1):
	# 前半の条件に当てはまるものを抽出
	if i < start_num + range_num:
		result_list.append(i)
	else:
		break

for i in range(end_num, start_num -1, -1):
	# 後半の条件に当てはまるものを抽出
	if i > end_num - range_num:
		result_list.append(i)
	else:
		break

# 重複削除
result_list = list(set(result_list))
# 昇順ソート
result_list.sort()

for num in result_list:
	print(num)
