javascript - Use js to implement red envelope distribution problem

Question

100 yuan is given to 10 people in red envelopes. The size of the red envelope is random and everyone can get a red envelope

Answer 1

rpAmount = 100
ppCount = 10
rpResult=[]
rpRnds = []
rpRndSum = 0
for(let i=0;i<ppCount;i++){let rnd = Math.random();rpRndSum+=rnd;rpRnds.push(rnd);}
rpRnds.forEach((rnd)=>{rpResult.push(rpAmount*rnd/rpRndSum)})
console.log('rpResult',{rpResult,sum:rpResult.reduce((acc,val)=>{return acc+val})})

Core idea:
The weight is directly determined by the random number, not the amount.

Answer 3

Idea: Use the random function to randomly allocate each time. The red envelope value obtained each time is greater than 0.01 and less than the remaining amount - the remaining number of people * 0.01. The last person can get all the remaining money
