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

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

Solution in Python (3.4.3) (judge verdict: Runtime Error)

A, B, K =map(int,input().split())

if B-A <= K:
  for i in range(A, B):
    print(i)
else:
  C = []
  for i in range(A, A+K):
    C.append(i)
  
  D = []  
  for i in range(B, B-K+1, -1) :
    D.append(i)

E = set(C) | set(D)
F = sorted(E)
print(F)
