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

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 = map(int, input().split())
if a + k - 1 < b:
  min_ = a + k - 1
else:
  for i in range(a, b + 1):
    print(i)
  exit(0)
max_ = b - k + 1
if max_ == min_:
  max_ += 1
for i in range(a, min_ + 1):
    print(i)

for i in range(max_, b + 1):
    print(i)
