Fireworks

One of the days of the hike coincided with a holiday, so in the evening at the camp, it was decided to arrange a festive fireworks display. For this purpose, the organizers of the hike bought two installations for launching fireworks and a huge number of shells for launching.

Both installations are turned on simultaneously. The first installation launches fireworks every aa minutes (i.e., after a,2a,3a,a, 2 \cdot a, 3 \cdot a, \dots minutes after launch). The second installation launches fireworks every bb minutes (i.e., after b,2b,3b,b, 2 \cdot b, 3 \cdot b, \dots minutes after launch).

Each firework is visible in the sky for m+1m + 1 minutes after launch, i.e., if a firework was launched after xx minutes after the installations were turned on, it will be visible every minute from xx to x+mx + m, inclusive. If one firework was launched mm minutes after another, both fireworks will be visible for one minute.

What is the maximum number of fireworks that could be seen in the sky at the same time?

Input

Each test consists of several test cases. The first line contains a single integer tt (1t1041 \le t \le 10^4) — the number of test cases. Then follow the descriptions of the test cases.

The first and only line of each test case contains integers aa, bb, mm (1a,b,m10181 \le a, b, m \le 10^{18}) — the frequency of launching for the first installation, the second installation, and the time the firework is visible in the sky.

Output

For each set of input data, output a single number — the maximum number of fireworks that can be seen simultaneously.

Note

In the first set of input data, the fireworks are visible in the sky for 55 minutes. Since the first installation launches fireworks every 66 minutes, and the second one every 77 minutes, two fireworks launched from the same installation will not be visible in the sky at the same time. At the same time, after 77 minutes from the start of the holiday, one firework from the first and one from the second camp will be visible. Thus, it is possible to see no more than 22 fireworks simultaneously.

In the third set of input data, 1717 fireworks will be visible after 112112 minutes:

  • 99 fireworks launched from the first installation at times [56,63,70,77,84,91,98,105,11256, 63, 70, 77, 84, 91, 98, 105, 112];
  • 88 fireworks launched from the second installation at times [56,64,72,80,88,96,104,11256, 64, 72, 80, 88, 96, 104, 112].
