I have two different solutions which handle this test very differently:

20 5
24
0.0 - 1.0
0.1 - 1.0
0.2 - 1.1
0.3 - 1.2
0.4 - 1.3
0.5 - 1.4
0.6 - 1.5
0.7 - 1.6
0.8 - 1.7
0.9 - 1.8
0.10 - 1.9
0.11 - 1.10
0.12 - 1.11
0.13 - 1.12
0.14 - 1.13
0.15 - 1.14
0.16 - 1.15
0.17 - 1.16
0.18 - 1.17
0.18 - 2.0
0.18 - 3.0
0.18 - 4.0
0.18 - 5.0
0.19 - 1.18
0 19

One of them might be even close to TLE, but both my solutions accepted here with time 0.015 s, which makes me think there is no such test in the list of tests.
I think this test should be added...

Your test has been added. 1 author lost AC after rejudge. Thanks and feel free to send more tests to support email.
