CF w1d3 A. Minimum Integer

You are given q queries in the following form:

Given three integers li, ri and di, find minimum positive integer xi such that it is divisible by di and it does not belong to the segment [li,ri].

Can you answer all the queries?

Recall that a number x belongs to segment [l,r] if l≤x≤r.

Input

The first line contains one integer q (1≤q≤500) — the number of queries.

Then q lines follow, each containing a query given in the format li ri di (1≤li≤ri≤109, 1≤di≤109). li, ri and di are integers.

Output

For each query print one integer: the answer to this query.

Example

input
5
2 4 2
5 10 4
3 10 1
1 2 3
4 6 5
output
6
4
1
3
10
