This article mainly introduces to Xiangxu the ASP.NET code that can easily realize red envelope grabbing on WeChat. It has a certain reference value. Interested friends can refer to it.

Everyone in the group is playing Grabbing red envelopes, sending them out again, grabbing them again after sending them out, is simply boring. Programmers are interested in how to implement it. Here I briefly talk about the implementation ideas, and attach the dome. The code is a bit low, but fortunately it is implemented. The specific content is as follows

Text

##100 yuan and 30 red envelopes

50 yuan and 13 red envelopes

10 red envelopes per block

2. Each red envelope must have money
3. Try to make it evenly distributed, otherwise it will be meaningless to grab the red envelopes

Implementation ideas1. First, determine the minimum unit, here it is accurate to the minute. I use int type for calculation here, and the results are all int type
2. The data is even, here 13. Remainder processing, when the data is averaged to 20 red envelopes, it must be different from the total amount. Deviation, at this time we have to refund more and make up less. If it is greater than the total amount, let the one with the larger amount reduce it (total amount/total number of people). If there is still something left, let the one with the second largest amount reduce it until this is completed. Until there is a vacancy, and vice versa.
4. Disrupt the order. Careful gardeners may find that red envelopes are in order. We must simply write a function to disrupt it.
