KIDx's Pagination
Time Limit: 2000/1000MS (Java/Others) Memory Limit: 128000/64000KB (Java/Others)
Problem Description
One Day, KIDx developed a beautiful pagination for ACdream. Now, KIDx wants you to make another one.
The are n pages in total.
The current page is cur.
The max distance to current page you can display is d.
Here are some rules:
- The cur page button is disabled.
- If cur page is the first page, the button "<<" should be disabled.
- If cur page is the last page, the button ">>" should be disabled.
- If the button "x" is disabled, print "[x]"; else print "(x)".
- You should not display the "..." button when there is no hidden page.
You can assume that the button "..." is always disabled.
Input
There are multiple cases.
Ease case contains three integers n, cur, d.
1 ≤ n ≤ 100.
1 ≤ cur ≤ n.
0 ≤ d ≤ n.
Ease case contains three integers n, cur, d.
1 ≤ n ≤ 100.
1 ≤ cur ≤ n.
0 ≤ d ≤ n.
Output
For each test case, output one line containing "Case #x: " followed by the result of pagination.
Sample Input
10 5 2
10 1 2
Sample Output
Case #1: (<<)[...](3)(4)[5](6)(7)[...](>>)
Case #2: [<<][1](2)(3)[...](>>)
Hint
Case 1:
Case 2:
