LeetCode 2050. Parallel Courses III【记忆化搜索,动态规划,拓扑排序】困难

默认输出是Buffer对象

const { execSync } = require('child_process')

let out = execSync("echo 'hi'")
console.log(out);
// <Buffer 68 69 0a>

需要转为字符串

const { execSync } = require('child_process')

let out = execSync("echo 'hi'")
console.log(out.toString());
// hi
