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

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

l = list(map(int, input().split()))
a = l[0]
b = l[1]
c = l[2]

ss = []
ll = []
def checkK(x,y,z):
    if y - x + 1 <= z:
        counter = int(x)
        while counter != y:
            ss.append(counter)
            counter = counter + 1
        for i in range(len(ss)):
            print(ss[i])
    else:
        for i in range(c):
            ll.append(a+i)
        for i in range(c):
            ll.append(b-c+i)
        for i in range(len(ll)):
            print(ll[i])
        
checkK(a,b,c)
