New Year is coming and you are excited to know how many minutes remain before the New Year. You know that currently the clock shows $$$h$$$ hours and $$$m$$$ minutes, where $$$0 \le hh \lt 24$$$ and $$$0 \le mm \lt 60$$$. We use 24-hour time format!

Your task is to find the number of minutes before the New Year. You know that New Year comes when the clock shows $$$0$$$ hours and $$$0$$$ minutes.

You have to answer $$$t$$$ independent test cases.

Input

The first line of the input contains one integer $$$t$$$ ($$$1 \le t \le 1439$$$) — the number of test cases.

The following $$$t$$$ lines describe test cases. The $$$i$$$-th line contains the time as two integers $$$h$$$ and $$$m$$$ ($$$0 \le h \lt 24$$$, $$$0 \le m \lt 60$$$). It is guaranteed that this time is not a midnight, i.e. the following two conditions can't be met at the same time: $$$h=0$$$ and $$$m=0$$$. It is guara
