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: Wrong Answer)

A = list(map(int,input().split()))
a = 0
k  = []
for c in range(A[0],A[1]+1):
  print(c)
  a += 1
  if a== A[2]:
    break;
a = 0
for c in range(A[1], A[0], -1):
  if a == A[2]:
    break;
  k.append(c)
  a += 1
k = sorted(k)
for i in k:
  print(i)
