求出其中两类鸡分别与另外一类鸡的关系方程式 条件设定为三类鸡数量都为整数即可 完整代码如下：
const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;
void async function () {
// Write your code here
while(line = await readline()){
if (line) {
let arr = Array.from(Array(21).keys());
let res = [];
for (let i = 0; i < arr.length; i++){
let j = (100-7*i)/4;
let k = (300+3*i)/4;
if (j >= 0 && Number.isInteger(j) && k >= 0 && Number.isInteger(k)){
console.log(i, j, k);
}
}
}
}
}()
