That's what I did too. The only problem is that building the graph is not linear time, I believe. Still, it was fast enough to get it accepted in 0.012s.

### Re: 10099 - The Tourist Guide

Have you actually check the sample input/output? You code produces

Minimun Number of Trips = 4

when it should be

Minimun Number of Trips = 5

Anyways, your error is in the line with the division and ceiling in the output. 99/24 = 4 since it is an integer division, so ceiling is useless.

### Re: 545

I honestly do not know what's wrong with my code. I used the square and double method, which worked perfectly well on 474, and is failing hard here. Eventually I took the suggestion of using BigInt, and got it accepted. I still have no idea what's wrong though, since both code gives the same output ...

### Re: 474 problem

### Re: 793 - Network Connections

I hate print blank line between test case so much. Judge will say WA instead of PE, which leads you to a wild goose chase.

On this case: 1 9 9 9 9 0 0 0 0 1 9 9 9 9 The code I just submitted and got AC with returns -1, if you'd rather believe your WA code and UVAtoolkit's 4 that's up to you, let us know if you can get AC with that logic. Others in this thread that have got AC agreed that it should be -1. My AC code ret...
