WeChat group red packet algorithm and group red packet algorithm

Group red packet algorithm and group red packet algorithm

Today is the last day of the Spring Festival. There is nothing to do. It is just that the students in the group will discuss the algorithm of group red packets.

A close-up algorithm is provided. The general idea is to find the red envelope that has been sent and find its random vibration slope.

Let's take a look at the algorithm:

# Coding = gbkimport randomimport sys # print random. randint (0, 99) # print "=", random. uniform (0, 0.99) def calRandomValue (min, max, total, num): print min, max, total, numtotal = float (total) num = int (num) min = 0.01if (num <1): returnif num = 1: print "% d: %. 2f "% (num, total) returni = 1total_money = total # rtotal = (total * 100-min * num * 100)/100 while (I <num ): max = total_money-min * (num-I) k = int (num-I)/2) if num-I <= 2: k = num-imax = max/kmonney = random. randint (int (min * 100), int (max * 100) monney = float (monney)/100total_money = total_money-monneyprint "% d the number of red packets received by individuals is %. 2f, balance: %. 2f "% (I, monney, total_money) I + = 1 print" % d: %. 2f, balance: %. 2f "% (I, total_money, 0.0) if _ name _ =" _ main _ ": min = sys. argv [1] max = sys. argv [2] total = sys. argv [3] num = sys. argv [4] calRandomValue (min, max, total, num)
