Javascript 生成5个随机数，总和等于100

Question

I saw several solutions in python and java here but I didn't find anything using javascript. How do I generate 5 random numbers whose sum is equal to 100?

// output: {10, 20, 50, 10, 10}

Answer 1

 let sum = 100 const numbers = [] for (let i = 0; i < 4; i++) { const randomNumber = Math.floor(Math.random() * sum) sum -= randomNumber < 0? 0: randomNumber numbers.push(randomNumber < 0? 0: randomNumber) } numbers.push(sum) console.log(numbers, numbers.reduce((a, b) => a + b, 0)) // 5 random numbers of sum 100
