implementation of dijkstra s shortest path algorithm in java

The factorial algorithm is as follows: 0 to 20 of the factorial: 0! =1, (the factorial of 0 is present) 1! =1,2! =2,3! =6,4! =24,5! =120,6! =720,7! =5040,8! =403209! =36288010! =362880011! =3991680012! =47900160013! =622702080014! =8717829120015! =130767436800016! =2092278988800017! =35568742809600018! =640237370572800019! =12164510040883200020! =2432902008176640000 and when N≥5, n!

follows: 3 1 2 5 4 6 9 7 10 8 To this first round of "probing" really ended. At this point, the Datum number 6 is the dividing point, the number on the left of 6 is less than or equal to 6, and the number on the right is greater than or equal to 6. Review the process just now, in fact, Sentry J's mission is to find less than the number of benchmarks, and Sentinel I's mission is to find more than the number of the benchmark, until I and J meet up. OK, the explanation is complete. Now that the

play the micro-letter red envelopes bad luck 20 Yuan 3 person points I also smoked over 0.01 yuan. Concurrent volumes can also be very large. So my code is simply to give everyone a random number (a random number range is the number *100), add these people's random numbers together and then calculate the percentage of random numbers per person. Divide the red envelopes by this percentage. The above is a small set to introduce the Java
