CF1987A Upload More RAM

哦不，$ForceCodes$ 服务器内存不足！幸运的是，您可以通过上传一些$ RAM$ 来帮助他们！ 您要上传 $?GB$ 的 $RAM$。每秒，您将上传$0$或$1GB$ 内存。但是，您的网络速度是有限制的：在任何对连续秒数，最多只能上传总共 $1GB$ 的 $RAM$。 查找上传所需的最短秒数 $nGB$ 或 $RAM$！

每个测试都包含多个测试用例。输入的第一行包含单个整数$?$ ( $ 1\le t \le10^4$ ） —— 测试用例的数量。测试用例的描述如下。 每个测试用例的第一行也是唯一的一行包含两个整数$n$和$k$( $1\le?,k\le100 $） —— 要上传的$GB$数和时间窗口的长度。

对于每个测试用例，输出一个整数——上传所需的最小秒数 $nGB$ 或 $RAM$。

In the first test case, you can upload $ 1 $ GB of RAM per second, so to upload $ 5 $ GBs, you need $ 5 $ seconds. In the second test case, you can upload $ 1 $ GB in the first second, $ 0 $ GBs in the second second, and $ 1 $ GB in the third second, which in total adds up to exactly $ 2 $ GBs of uploaded RAM. In the third test case, you can upload $ 1 $ GB in the first second, $ 0 $ GBs in the second second, $ 0 $ GBs in the third second, and $ 1 $ GB in the fourth second, which in total adds up to exactly $ 2 $ GBs of uploaded RAM.
