无重复数组
https://www.nowcoder.com/practice/d2fa3632268b41df9bc417b74802ad8c
const _getUniqueNums = (start,end,n) => {
end - 1;
lst = []
// 补全代码
while(true){
let num = Math.floor(Math.random() * end) + start;
if(lst.includes(num)) continue;
lst.push(num);
n--;
if(n === 0) break;
}
return lst
}
循环生成随机数并存入数组中即可，如遇到重复的直接跳过进入下一次循环
