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.

Sample Input 1

3 8 2

Sample Output 1

3
4
7
8

3 is the first smallest integer among the integers between 3 and 8.

4 is the second smallest integer among the integers between 3 and 8.

7 is the second largest integer among the integers between 3 and 8.

8 is the first largest integer among the integers between 3 and 8.

Sample Input 2

4 8 3

Sample Output 2

4
5
6
7

Solution in Python (3.8.2) (judge verdict: Accepted)

a, b, k = map(int, input().split())

min = [0] * k
max = [0] * k

for i in range(k):
  if a+i > b:
    break
  min[i] = a+i

for n in range(k):
  if b-n < a:
    break
  max[n] = b-n

ans = min + max
ans = set(ans)
ans = list(ans)
ans.sort()

for j in ans:
  if j == 0:
    continue
  print(j)
