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

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

Solution in Python (3.4.3) (judge verdict: Wrong Answer)

a,b,k = input().split()
a=int(a)
b=int(b)
k=int(k)
if b-a < k:
  k=b-a
  x=[i for i in range(a,a+k)]
  y=[i for i in range(b,b-k,-1)]
  z=x+y
  z.sort()
  z=set(z)
  z=list(z)
  z.sort()
  for i in range(len(z)):
    print(z[i])
